Paper Abstract

In this paper we use digital projection moiré (DPM) method to analyze the non-linear behavior of sandwich beams with compliant foam core. These cores are highly flexible with respect to the face sheets and their behavior is associated with localized effects in the form of localized displacements and stresses, which in turn influence the overall behavior of sandwich beams. In this study we compare the results of three point bending with Finite Element Analysis (FEA) results that are obtained from the ABAQUS finite element code. We have shown that DPM experimental results are in good agreement with FEA simulations. It is suggested that the presented method can be used as a simple, advantageous and user friendly whole-field testing technique for many applications in evaluation of composite materials and sandwich structures.
