Description of evolving anisotropy at large strains

Harrysson, Magnus LU and Ristinmaa, Matti LU (2007) In Mechanics of Materials 39(3). p.267-282
Abstract
A description of texture evolution at large strain plasticity is developed. Texture evolution is defined in terms of changes taking place in the substructure of the material. The changes in the substructure are specified by means of a tangent map defined in the same manner as for the continuum in terms of a multiplicative decomposition. It is shown that the description of the changes in the substructure can be formulated in a way completely analogous to the description of the deformation of the continuum. Within the framework of thermodynamics the evolution of the substructure, driven by its conjugated force emerging from the dissipation inequality, is studied. The performance of the model presented is studied in relation to off-axis... (More)

Within the framework of thermodynamics the evolution of the substructure, driven by its conjugated force emerging from the dissipation inequality, is studied. The performance of the model presented is studied in relation to off-axis uniaxial stress, the evolution of the substructure being compared with experimental findings. In addition, two different evolution laws for cubic material symmetry are investigated. (Less)
