Experimental and Numerical Assessment of Bamboo–Coir Hybrid Composite Panels for Formwork Systems C. Bhargavi, K. S. Sreekeshava, Manish S. Dharek, B. K. Raghu Prasad, J. V. Raghavendra Applied Mechanics, 2026 This study evaluates bamboo–coir hybrid composite panels developed for formwork applications using an 80:20 fiber–matrix ratio and a 50:50 bamboo-to-coir distribution. The novelty of this study lies in the combined assessment of formwork-relevant mechanical performance, Mode I and Mode II fracture behavior, finite element validation and post-fracture microstructural correlation for a high fiber volume fraction natural fiber hybrid panel. Mechanical, durability, fracture, numerical and microstructural investigations were performed and benchmarked against 10 mm thick construction-grade plywood. The hybrid panels exhibited a density of 805 ± 10.84 kg/m3, which is within 0.7% of plywood, a tensile strength of 50.20 ± 2.85 MPa, representing an increase of 41.8% over plywood, and a flexural strength of 38.60 ± 2.10 MPa, corresponding to an increase of 12.9% as compared to plywood. The impact energy absorption of hybrid panels was 7.85 ± 0.62 J, which is 26.6% greater than plywood. Mode I fracture testing yielded a fracture toughness of 456.65 ± 15.42 J/m2, corresponding to an increase of 9.3% over plywood, while Mode II fracture toughness yielded a value of 792.42 ± 30.18 J/m2, representing an increase of 13.7% over plywood. Finite element predictions deviated from experimental load–displacement responses by 5–13%. SEM observations identified fiber bridging, fiber pullout and interfacial sliding in the hybrid panels, consistent with the measured fracture energy values. The results indicate that bamboo–coir hybrid panels satisfy the mechanical and fracture performance requirements for reusable formwork systems.
An influence of nickel with heat treatment on the microstructure and fracture toughness of austempered ductile iron: Influence du nickel avec traitement thermique sur la microstructure et la ténacité à la rupture de la fonte ductile à trempe bainitique Subramanya Raghavendra, J. V. Raghavendra, Manjunatha Kuntanahalli Narayanappa, Chandra Shekar Anjinappa, K. G. Srinivas, B. Manjunatha Canadian Metallurgical Quarterly, 2023 In this study, unalloyed and nickel alloyed permanent moulded Austempered Ductile Iron (PMADI) samples are utilised to evaluate and compare properties such as tensile hardness and fracture toughness. All PMADI samples were austempered at 350°C for 150 minutes to improve mechanical properties. When compared to unalloyed PMADI samples, PMADI samples alloyed with 1.5% nickel showed better hardness, tensile, and fracture toughness characteristics. In addition to the microstructure examination on samples to determine the presence of feathery dispersion of Bainite, an X-Ray Diffraction Analysis was done to confirm the presence of austenite.
