Abstract

In the present work a method to obtain a true stress-true strain curve of an alloy by a full field digital image correlation measurement of the specimen surface kinematics, is presented. A preliminary set of parameters of a plasticity law is obtained to start up an automatized search algorithm, that includes, for each step a FE analysis in 3D. It’s also proposed a dual approach of the same search problem.
