IUTAM Symposium on Multiscale Modeling and Characterization of Elastic- Inelastic Behavior of Engineering Materials Held in Marrakech, Morocco on October 20-25, 2002

摘要

The topics presented were wide ranging and included many aspects of deformation and fracture in a variety of materials. Among the areas that were: Developments on the constitutive connections for inelastic deformation of crystalline media, using atomistic approaches to processes such as cross slip of dislocations, but more often using dislocation models of plastic flow through formalisms of dislocation dynamics but also using models of collective dislocation activity to model incipient patterning and strain hardening. Development of deformation textures in polycrystals. Problems involving strain gradient plasticity on the sub-micron scale. Problems involving twinning in crystal plasticity and in the context of shape memory behavior. Plasticity of amorphous and semi crystalline polymers. Plasticity and fracture-related damage development in heterogeneous materials, granular materials, and composites, including the role of grain boundaries. Problems involving fracture and its mechanisms ranging from brittle cleavage to ductile cavitational forms and brittle to ductile fracture transitions, as well as in cyclic deformations. A large number of other topics related to the general theme were also presented in both the main sessions and in the poster presentations.
