Constitutive Equations for Damaged Creeping Materials,
Abstract
Constitutive equations for a power-law incompressible isotropic matrix containing aligned facet cracks are presented. Applications are directed to a description of polycrystalline materials which undergo significant tertiary creep when subjected to load at elevated temperatures. The main goal of the work is to develop three-dimensional constitutive relations for this class of materials and microstructural damage, which are both physically sound and straightforward to implement into a finite element program. Certain important features of the structure for such relations are emphasized. Some numerical and closed form solutions are presented to quantify the equations within the framework of the differential self-consistent scheme.
