Abstract:
Stress concentration factors have been examined in a functionally graded material (FGM) plate with central holes in different shapes in this essay. The material properties change along the thickness of plate. ABAQUS software has been utilized for modeling of problem in which subroutine of ABAQUS sub-program was used for modeling of the targeted material. The considering shapes for hole in plate are circular and elliptical in which stress concentration factors have been studied in different modes in respective of ellipse diameters. Similarly, stress concentration factors have been analyzed in the plate for various coefficients of FGM function. The results show that changes in material properties and the shape of hole in plate affect the stress concentration factor around the hole. An experiment was implemented to determine verification of results from Finite Element Method (EFM).
