Abstract
This paper presents an inverse method for the identification of the in-plane orthotropic apparent engineering constants of bi-axially loaded composite materials using cruciform specimens. The full field displacements are identified by a digital image correlation technique. From the displacement field a strain field is computed and compared with finite element strain results of the experiment. The apparent engineering constants are unknown parameters in the finite element model. Starting from initial values, these parameters are updated till the computed strain field matches the experimental strain field, In a first stage, global apparent engineering constants were determined, In this stage a more local determination of the engineering constants is studied.
