Inverse procedures for material characterization using dynamic response

Abstract

Computational inverse procedures for the characterization of material parameters using measured dynamic responses are discussed for structures made of composite materials and functionally graded materials. The finite element method and hybrid numerical method are applied as forward solver to obtain numerical results of dynamic response of structures. A number of optimization techniques used for the inverse analyses are presented to minimize the error function of numerical and experimental response. Several examples demonstrated validity and efficiency of the inverse procedures for material property characterization.
