  • Structural simulation of Ti–Ha–CaCO3 biocomposites using finite element analysis (FEA) for biomechanical stability of hip implant
    Hassan Kobe Ibrahim, Mathew Sunday Abolarin, Asipita Salawu Abdulrahman, Peter Olorunleke Omoniyi, Rasheedat Modupe Mahamood, et al.
    International Journal on Interactive Design and Manufacturing, 2025
    The structural integrity of new biocomposite implants is critical in ensuring the success of biomedical implants under physiological loading conditions. Studying the stress distribution, deformation, and potential failure modes under different loading scenarios is complex, expensive, and time-consuming, as it involves repeated surgery on clinical assessment. The present study aims to investigate the biomechanical stability of hip implants made of a Ti–Ha–CaCO3 biocomposite using finite element analysis. The Ti–Ha–CaCO3 biocomposite was modeled and simulated using Solidworks. The model mesh was generated to represent the implant’s geometry accurately, and normal human activities (standing and jumping) were considered the boundary conditions with the lower part of the femur fixed. The model was subjected to static loading following ISO 7206-4 with an equivalent load of 2300 N according to ASTM F2996-13 standard. The Ti–Ha–CaCO3 biocomposite demonstrated outstanding biomechanical stability under loading circumstances. The maximum von Mises stress (354.7 MPa) observed with the GSB-femur model in the implant was below the yield strength of the titanium implant, indicating that the implant can withstand applied loads without experiencing permanent deformation. However, 74.11 MPa was obtained as acceptable von Mises stress using GSB intramedullary rods for bone fixation. The most stable implant is DSB, with the lowest displacement value of 2.68 mm. Low equivalent strains were achieved for all the implants, as the highest strain (0.012) was obtained in the simulation of the stem DSB-femur model. Low-stress signals (SS) were obtained for the implant-femur models, indicating they are suitable for replacing bone for that loading. The DSB (7.19) is the most suitable among the studied stem-femur models, and GSB (0.87) remains the suitable intramedullary rod-femur model with the lowest SS.

  • Performance evaluation of aluminum-in-pot evaporative cooler
    Olalekan Popoola, Haruna Issa, Hassan Ibrahim, Peter Omoniyi, Isaac Adegun
    Brazilian Journal of Biosystems Engineering, 2025
    Cooling applications by refrigeration and air-conditioning require electricity as a source of energy not abundantly available in sub-Saharan African countries. Post-harvest losses of vegetables are caused by poor storage facilities, poor transportation systems, and lack of processing facilities. The current study aimed to evaluate the performance of developed solar-powered Aluminium-in-pot evaporative coolers lined with clay and charcoal blends for the preservation of tomatoes. The evaporative cooler consisted of Aluminium pots inserted into an earthenware mould pot, and the space between the two pots filled with lining media of clay, charcoal, and blends of the two in different ratios. The dry bulb temperature of the ambient air, inner temperatures of the cooling chambers, and relative Humidity were measured using fresh tomatoes as a load for the coolers. The temperature variations of the coolers were recorded for fifteen consecutive days. It was found that the inner temperatures for the five evaporative coolers were significantly different from the dry bulb temperature of the ambient. The temperature of sample E had the lowest temperature range of 19.65 °C to 23.65 °C for the no-load test, 21.15 °C to 25.29 °C for the load–load-test (better boy), and 21.1 to 23.25 °C for the load test (Plum). The daily temperature in the coolers dropped significantly to a range of between 3.4 °C to 10.46 °C with a corresponding daily RH range of 30.93% to 39%. The variations in the efficiency of Sample E were found to be averagely 84% at no load, 72% when loaded with Better Boy and 77% when loaded with Plum tomatoes. The aluminium in pot evaporative cooler could be used for a short-term preservation of tomatoes in remote areas where electricity is not available.

  • Biomechanical and Physical Properties Selection of Ti-Ha-CaCO3 Biocomposite Prostheses for Replacement of Bone Atrophy
    H. K. Ibrahim, M. S. Abolarin, A. S. Abdulrahman, O. Adedipe, U. G. Okoro
    Nigerian Journal of Technological Development, 2024
    Traditional prosthetic materials often lack the desired properties to mimic the mechanical behaviour of natural bone, leading to complications and reduced implant longevity. This study aims to conduct a biomechanical and physical properties selection analysis for biocomposite prostheses' suitable for replacing bone atrophy. This involves evaluating the mechanical properties of developed biocomposites with different structures (dense, porous and gradient) to ensure compatibility with the mechanical properties of bone. The radar chart was adopted to compare and evaluate the mechanical strength of various biocomposite implants and identify the most suitable prosthesis for load-bearing bone replacement. The study utilises powder metallurgy, scanning electron microscopy (SEM), and ImageJ software to produce and characterise the pore size distribution of the biocomposites, respectively. The findings of this study revealed the gradient and porous biocomposites exhibited desired mechanical properties with porosity of 20.67 and 27.72 % pore size up to 134 and 256 μm, compressive strength of 174 and 149.29 MPa and compressive modulus of 30.42 and 28.3 GPa respectively. The SEM analysis, coupled with pore size distribution and porosity percentage measurements, offers valuable information for designing and fabricating biomaterials with enhanced properties. The gradient biocomposite was identified to be the best sample for load-bearing bone replacements by the selection analysis because of its high compressive strength and low modulus, which is within the established cortical bone mechanical properties.
  • Development and analysis of friction material for eco-friendly brake pad using seashell composite
    Adebayo Adekunle, Mojeed Okunlola, Peter Omoniyi, Adekunle Adeleke, Peter Ikubanni, et al.
    Scientia Iranica, 2023
    Asbestos has been banned in many countries as a result of its negative effects on the environment and human health. As a result, a human-friendly friction material is required to replace asbestos in brake pads. Hence, the powder metallurgy technique was undertaken to develop friction material from locally sourced asbestos-free materials. Seashell was used as base elements with other additives. The filler material considered had a particulate size of 300 µm

  • Mechanical and Corrosion Protection Characteristics of CNTs/epoxy resin Nanocomposite Coating on Buried API 5L X65 Steel Storage Tank
    Aliyu Shehu Buhari, Asipita Salawu Abdulrahman, Sunday Albert Lawal, Ambali Saka Abdulkareem, Rasheed Aremu Muriana, et al.
    Journal of Physical Science, 2023
    The storage of petroleum products in buried metal tanks to ensure safety is common practice. However, the integrity of these tanks could be compromised by soil corrosion with economic and environmental consequences. This study examines carbon nanotubes mechanical and anti-corrosive capabilities (CNTs) and epoxy resin coating on steel tanks. The presence of corrosive ions, resistivity, and pH values were all tested in the soil sample. CNT was mixed in proportions of 1.5, 2.5, 3.5 and 4.5 weight percent of epoxy resin to create the coatings. The morphology of uncoated steel, epoxy, and CNTs/ epoxy resin-coated steel specimens was studied using high-resolution scanning electron microscopy (HRSEM) equipment with energy dispersive x-ray spectroscopy (EDX). Electrochemical impedance spectroscopy (EIS) was used for corrosion analysis, and the morphological result was established. The average ions content soil samples showed 272 mg/kg chloride, 467.20 mg/kg sulphate and 167.40 Ω-m for the average resistivity value. The sample’s pH was acidic because it fell within 6.11–7.48. The tensile strength, hardness, and tensile modulus of epoxy resin with CNTs increase with CNTs. The addition of 3.5% CNTs has the best effect on the mechanical strength of the composite. The nanocomposite coatings exhibited considerably superior conductors, according to the EIS investigation. Thus, the hybrid of epoxy and CNTs increases the hydrophobicity of the coated surface.
  • Thermo-economic feasibility analysis of trilateral-cycle power generators for waste heat recovery-to-power applications
    Habeeb A. AJIMOTOKAN, Isiaka AYUBA, Hassan K. IBRAHIM
    Journal of Thermal Engineering, 2022
    The trilateral cycle (TLC), a promising alternative waste heat recovery-to-power cycle, is receiving increasing attention due to feats such as the high thermal match between the exergy of the heat source temperature profiles and its working fluid. Although the TLC has neither been broadly applied nor commercialised because of its thermo-economic feasibility considerations. This study examined the thermo-economic analysis of different TLC power generator configurations; i.e., the saturated subcritical simple (non-recuperative) and recuperative cycles using n-pentane as the working fluid for low-grade waste heat recovery-to-power generation. Based on the thermodynamic and economic analyses, the feasibility analysis models of the cycles were established using Aspen Plus, considering efficiency, cost, and expected operating and capacity factors. Furthermore, the capacity factor, specific investment cost (SIC), and payback period (PBP), among other, were used to evaluate the cycle design configurations and sizes. The SICs of the simple and recuperative TLCs were 3,683.88 $/kW and 4,220.41 $/kW, and their PBPs were 8.43 years and 8.55 years, respectively. The simple TLC had a lower investment ratio of 0.24 compared to an investment ratio of 0.28 for the recuperative TLC. These economic values suggest that the simple TLC is more cost-effective when compared with the recuperative TLC because the recuperation process does not recompense the associated cost, making it unattractive.
  • Numerical Evaluation of Fatigue Crack Growth of Structural Steels Using Energy Release Rate with VCCT
    Yusuf O. Busari, Yupiter H. P. Manurung, Martin Leitner, Yusuf L. Shuaib-Babata, Muhd F. Mat, et al.
    Applied Sciences Switzerland, 2022
    This research presents the numerical evaluation of fatigue crack growth of structural steels S355 and S960 based on Paris’ law parameters (C and m) that are experimentally determined with a single edge notched tension (SENT) specimen using optical and crack gauge measurements on an electromotive resonance machine at constant amplitude load. The sustainable technique is replacing destructive, time-consuming and expensive approaches in structural integrity. The crack propagation is modelled using the 3D finite element method (FEM) with adaptive remeshing of tetrahedral elements along with the crack initiator elements provided in simulation software for crack propagation based on linear elastic fracture mechanics (LEFM). The stress intensity is computed based on the evaluation of energy release rates according to Irwin’s crack closure integral with applied cyclic load of 62.5 MPa, 100 MPa and 150 MPa and stress ratios of R = 0 and 0.1. In order to achieve optimized mesh size towards load cycle and computational time, mesh and re-mesh sensitivity analysis is conducted. The results indicate that the virtual crack closure technique VCCT-based 3D FEM shows acceptable agreement compared to the experimental investigation with the percentage error up to 7.9% for S355 and 12.8% for S960 structural steel.
