Abstract

This paper deals with the analysis of the mechanical response of an aluminium multi-crystal specimen subjected to a tensile load. Two different techniques are used for this purpose: the grid method to obtain strain maps and infrared thermography to deduce heat source distributions from temperature fields. Significant differences between the grains in terms of mechanical response are observed. Experimental results are compared to numerical results obtained with a suitable FE package. A good agreement is observed apart from very localized phenomena occurring near the boundaries of the grains which are not predicted by the FE model
