This article reviews recently developed methods for constitutive parameter identification based on kinematic full-field measurements, namely the finite element model updating method (FEMU), the constitutive equation gap method (CEGM), the virtual fields method (VFM), the equilibrium gap method (EGM) and the reciprocity gap method (RGM). Their formulation and underlying principles are presented and...
This paper presents a method of identifying unknown parameter and force histories for nonlinear structures. The nonlinearities treated are those that arise from large deflections and rotations and/or from material behavior in the form of elastic-plastic and hyperelastic responses. The method is based on a sensitivity response approach in conjunction with a general finite element program; it can determine...
