Abstract
The caustic method is a non-contact measurement method using a laser ray. This method has been applied to evaluate contact forces and stress intensity factors. For the application of the caustic method, numerical simulation is necessary to evaluate the stress state from the caustic image. However, the theoretical simulation is not possible if the stress state is complex. In the paper, we propose to use ANSYS, which is general used FEM software, for the simulation. This method will be applicable for more complicated stress state.
