Abstract


One method of identifying parameters governing the behaviour of an elastic material covers the Virtual Fields Method (VFM). However, this method has been validated for only homogeneous materials. In the case of compound materials, the presence of strong gradients strains near the interface limits the potential of this method, which requires some adjustments. This work focuses on the validation of the VFM applied to a Bi-Material composed of Polymer and Epoxy. The results obtained are in correlation with the characteristics of components used
