The objectives of these lectures are:
  • To suggest that time is ripe to revisit the whole field of the mechanical behavior of materials. This is a field relevant for its engineering and technological applications as well as for its economical implications: but the conventional approach to it turns out to be inadequate to face the complexity of the process occurring during the transformations promoted by external mechanical action on a material. The fundamental physical fact is too often ignored that the “mechanical” transformation of materials are not purely machanical, but belong rather to the domain of non-equilibrium cooperative phenomena. Therefore, a comprehensive understanding of these transformations cannot be achieved on a purely mechanical basis, focussing the attention solely on mechanical quantities such as deformation and stress. It requires, for instance, that also temperature charges, associated with the production and fluxes of entropy contestually accompanying these transformations, should be carefully measured and considered.
