✦ Synopsis

This study proposes an efficient dynamic simulation method for non destructive evaluation and non destructive characterization using finite element method. The method consists of an efficient algorithm and modeling for an object with uniform cross section including different properties. The efficient algorithm discretizes an object into characteristic finite elements and derives a recurrence formula for unknown vector, and then solves the formula efficiently. Objects, which have defects, welding, joint and so forth, are modeled considering a shape of uniform cross section and material constants. Dynamic simulations for the Hopkinson bar test for anisotropic materials are presented.
