Residual Stresses in Composite Plates with Central Filleted Hole

This article deals with the residual stresses in stainless steel fiber-reinforced aluminum composite plates under in-plane loading that have a central filleted hole. In many cases, the residual stresses in the plates increase ability to carry a larger load. The dimensions of the central hole vary from square to circle by increasing fillet radii at the corners. In the study, the effects of the hole dimension, the fillet radius, and the orientation angles on the residual stresses are investigated using the finite element method (FEM) software ANSYS. Results are presented in tabular and graphical forms.
