Identification of the non-elastic material parameters by inverse modelling: A stress based approximation

Inverse methods are a modern alternative technique to traditional standard testing for the identification of material parameters. The material parameters in the numerical model are the unknown parameters which will be aimed to identify. In this paper an alternative iterative strategy for material identification is proposed. The concept of the proposed strategy is based on the material behavior under an applied load which is described by the stress-strain curve. The material parameters can be identified based on observation strain field and numerically stress field.
