“…A few articles are available on the application of FGM for SCF reduction at inclusion interface of circular or elliptical shapes. Further, the work on SCF reduction around rounded rectangular inclusion is not available in the literature and it is significant to analyze the rounded rectangular inclusion for SCF reduction because rounded rectangle is a usual inclusion shape (Jaiswal et al, 2022). Which is the prime motivation for the present work i.e., modeling and stress analysis of rounded rectangular inclusion enclosed by FGM layer.…”

The aim of the present work is to model and analyze stresses around rounded rectangular inclusion enclosed with functionally graded material (FGM) layer. The inclusion has been considered in an infinite plate which is subjected to far-field tensile stress. The extended finite element method (XFEM) has been used to model the inclusion with non-conformal mesh. The level set functions of circular and rectangular shapes have been used to trace the inclusion boundary with mesh. The FGM has been considered as continuous varying mixture of inclusion and plate materials with power law function along normal direction to the inclusion interface. Young's modulus has been assumed to vary within FGM layer, whereas Poisson's ratio is kept constant. The stress distribution and stress concentration factor (SCF) have been analyzed for different geometrical and FGM parameters. It has been observed that XFEM with level set method efficiently model the difficult shape inclusions such as rounded rectangle. Applying the FGM layer smoothens the stress distribution around rounded rectangular inclusion and significantly reduces SCF. The position of maximum stress shifted from the inclusion interface toward the FGM layer interface. The least SCF has been noted with power law index n = 0.5 and FGM layer thickness t = r.

“…Jaiswal presented in a recent paper a methodology to model a functionally graded material (FGM) using FEM based on ANSYS to reduce the stress concentration by applying an FGM ring around the rectangular slot that is subjected to a tensile load, obtaining as a result that the stress reduction by this method is reduced compared to the case of homogeneous material and by modifying the parameters of the FGM ring the magnitude of the reduction can be controlled [19] . Subsequently, Rani presented a work that focused on numerically analyzing the concentration of stresses around the central elliptical inclusion coated by FGM using Extended Finite Element Method by preparing a MATLAB code.…”

Two-dimensional finite element analysis was used for stress concentration factors estimation in a wide range of bar-ellipse height and height-width elliptical hole ratios in a tensile bar. Least squares polynomial equations were fit to the design points. These equations agreed and tension stress concentration factor for elliptical holes was described. Such equation reproduces the curves and through its derivative the optimal values that minimize the concentration factor are estimated. The path of the minimal concentration factor was illustrated in a contour plot.

The present analysis is conducted for the evaluation of contact pressures of axisymmetric shells made of laminated composites or functionally graded materials. This class of problems is usually called the Signorini–Fichera problem (unilateral constraints) and can be solved as the lower-bound problem. The numerical solution of this problem is proposed both for symmetric and unsymmetric shell configurations. The first-ply-failure of such structures is considered. It is demonstrated that the failure occurs at the end of the contact area corresponding to the appearance of stress concentration of radial concentrated forces.
