This paper presents a numerical evaluation system of noninvasive evaluation of fractured bone based on speckle interferometry. The system simulates the deformation of an object using a particle method. Out-of-plane vibration of the object surface is obtained as numerically speckle fringes generated by a speckle interferometry based on wave optics. In the present numerical simulation, the velocity of impact object and the thickness of the external layers of three-layer object are employed as simulation parameters, and their influence on the evaluation index of internal state is examined by using the proposed numerical evaluation system. The relation between experimental parameters and the evaluation index is shown and the usefulness of the proposal system is shown.
