  • Finite element and photoelastic study of stress fields in curved plates with identical holes

    Mechanics Based Design of Structures and Machines, 2026
    Assessment of stress is crucial in failure analysis of a machine component. Curved plates have a wide range of industrial applications. Circular hole is one of the most commonly observed singularities, raising the stress concentration. Studies have been done to observe the interaction effect of circular holes in flat plates, however, their behavior in curved plates needs to be closely examined. Finite element simulations are carried out to analyze the stress distribution in different geometries. The findings show that stress fields associated with adjacent singularities exhibit mutual influence, leading to localized amplification or attenuation of stress concentration in their vicinity and also reduce the magnitude of stress concentration factor when placed at optimum distance. Finite element analysis results are experimentally validated using Photoelasticity. The findings in this study induce valuable guidance for failure analysts and engineers to better understand stress distribution in industrial applications.
  • Evaluation of stress distribution in cylindrical roller bearings with spalling defects through finite element and photoelastic analysis

    Stress analysis of contact zones in bearing is of paramount importance as it plays a crucial role in deciding its performance and durability. Operational issues such as misalignment, improper loading and lubrication failure often lead to surface defects such as spalling, which accelerate premature failure. This study analyses an NU356 cylindrical roller bearing to investigate spall-induced stress concentrations. The analysis demonstrates that changing the angular orientation of the notch significantly influences stress distribution in the bearing, with orientations near the vertical axis (0°–10°). Stress analysis is performed through Finite Element Analysis for notch locations ranging from 10° to 90°, considering the bearing’s horizontal and vertical symmetry. Numerical predictions are experimentally validated using photoelastic stress analysis, confirming the accuracy of the simulation approach and supporting improved bearing failure assessment.

  • Effect of curvature on stress concentration factor in a thin plate with circular holes and plate with V-notches under tensile load
    Ramit Chugh, Shubhrata Nagpal, Shubhashis Sanyal
    Mechanics of Advanced Materials and Structures, 2025
    Analysis of stress is one of the most crucial aspects in machine design. Curved plates have emerging significance in various fields such as biomedical, aerospace, and other industrial applications. Circular holes and V-notches are commonly observed singularities in these curved plates. Studies have been carried out to observe the effect of these singularities in flat plates, however, their behavior in curved plates is less explored. Finite element analysis (FEA) of curved plates with circular holes and curved plates with V-notches is done to observe the effect of curvature on stress fields near the singularity. The findings show that the curvature of the plate directly affects the stress concentration near singularity. The simulation results are experimentally validated using photoelasticity. The findings deliver actionable guidance for engineers regarding design of curved plates with singularities.

    Smart Technologies for Improved Performance of Manufacturing Systems and Services, 2023
    The manufacturing industry across the globe is accelerating at a rapid pace, and India is emerging as a preferred hub for manufacturing in modern welding processes. Improving the performance of manufacturing using the traditional methods for calculating welding strength on aluminum alloy has stirred serious deliberation. The parameter has shown the effect on the Friction Stir Welding (FSW) tool in the stir welding process. The variety of work on the stir welding process is discussed with special analysis on past performance. Optimizing the strength variation of a welding joint under two modes of preheating temperature on the workpiece, then applying a variation of cooling medium after preheating can change the grain structure of the workpiece. The FSW process is passed once, then the strength specimen is prepared for testing as per ASTM dimensions, Results of the strength test are discussed and optimized. Based on the optimal parameters of both materials, these similar materials were welded, and their strength analyzed by microstructure. Also, it is applied to another multi-optimization technique which compares and validates the process parameters for maximum welding strength. Significant parameters of the response were obtained by applying ANOVA on pure aluminum materials.
