Abstract
The method of caustics is one of the optical measurement method witch is used to determine the stress intensity factor of a crack tip and the contact force. Determining physical parameters using this method, simulation of caustic images are necessary based on the theory of elasticity or the numerical analysis. We developed a simulation system of the caustic image adopted to the general finite element method software. Using this system, gradients of a stress state are easily/automatically calculated for the caustic image simulation. The developed system was applied to 2-Dimensional crack problem and confirmed the effectiveness the simulation system.
