In this paper a methodology to analyse the shear behaviour of aluminium foam with closed cells is proposed.

Abstract
In this paper a methodology to analyse the shear behaviour of aluminium foam with closed cells is proposed. A biaxial load device expressly designed and the elaboration with Digital Image Correlation technique of the data acquired during the test with a CCD camera allowed determining the displacement and strain fields. This procedure made possible to evaluate the procedure as suitable or not for conducting a shear characterization for metallic foam. The curves obtained showed an initial elastic outline followed by the yield plateau, a peak load and a rapid load drop.File in questo prodotto:
