The « Matériaux Cristallins sous Contrainte » (Crystalline materials under stress) group works to uncover the underlying mechanisms involved in strain accommodation and relaxation of materials undergoing internal stresses or submitted to applied external stresses. We aim at studying the influence of these mechanisms on the macroscopic properties, which can be mechanical, electronic, optical or magnetic properties, depending on the studied material.
A wide range of materials is investigated, ranging from model materials to materials designed for industrial applications. These latter are either developed in the group using different techniques or processed by collaborating groups or industrial companies. To reach these objectives, we have developed an approach based on complementary structural, chemical and microstructural analyses coupled with modelling at different scales.
