Abstract

A Digital Image Correlation technique is used to develop and validate a new biaxial compression set-up. Some experimental test have been performed under proportional and nonproportional loading conditions with the experimental set-up. During these test, a particular attention is paid to the appearance and the disappearance of martensite plates during the loading path. By using a long distance microscope with a CCD camera, we show the importance of the mechanical loading path shape on the martensite formation.
