This paper is concerned with development of guided wave simulator on piping diagnostic system. First, a mathematical model of inspe ction procedures is described by a set of dynamical linear elastic equations in three spatial dimensions. Secondly, the numerical s cheme of the inspection model is given by using FDTD method. Finally, some numerical experiments are shown in order to assure the ap plicability of the proposed scheme to piping test. ...
