Time dependent behavior and failure of materials and structures

This first lecture in this module aims at giving the basic concepts of durability of materials and structures in the contexte of a sustainable development of society, seen more and more not as a simple technical issue but also as an economic and environmental one.
The main objective of this lecture is to give the definitions of durability, a historical evolution of concepts, the place of durability in the general framework of sustainability. Some technical concepts (stress, strain, yield surface, criterions) are also recalled
