Abstract

The objective of this chapter is to present a number of examples of application of the Virtual Fields Method (VFM) to polymer matrix fiber composites. Historically, composites have been the first materials considered for the VFM. Such composites possess two main features as far as their mechanical behavior is concerned: they are elastically anisotropic and they are prone to damage in the form of cracks, delamination, and/or fiber breakage. The first part of the chapter deals with the measurements of anisotropic stiffness components of composites. In-plane and through-thickness properties are first addressed and then bending properties for thin plates. Then, two applications related to damage are presented. The first one concerns the identification of a damage model when damage develops under loading. The second one deals with the detection and evaluation of a pre-existing damage caused, for instance, by some impact event on a thin panel. Finally, a recent application in the field of high strain rate testing is also presented.
