Abstract
A stress analysis method for a model with initial stresses is presented, herein referred to as a residual stress model. The stresses applied to the residual stress model are obtained from two resultant stresses by applying loads of different magnitudes. The residual stress model used to test the proposed method is a circular disk with frozen stresses that is subjected to a diametral compressive load at an angle of 31°. The applied stresses and residual stresses on the model were precisely obtained by numerical simulations using the proposed method.
