Efficient identification of material parameters based on experiments providing full‐field kinematics

Abstract Performing predictive and accurate simulations of anisotropic, nonlinear materials requires not only to construct an appropriate constitutive model describing the mechanical behavior, but also devise a methodology which enables quantitative identification material parameters. Nowadays, full‐field measurements displacements strains are considered as effective tool for characterization. In scope this work, first, is reformulated such that parameters appear linear in equations. Second, kinematics directly inserted into discretized equilibrium equation. This definition quadratic objective function terms differences discrete internal external forces. Third, one single inhomogeneous experimental setup designed excite all deformation modes model.
