| Abstract: | A generalized model for materials with inelastic strain and damage which is applicable to metal matrix composites is developed. The constitutive framework is based on a continuum mechanics approach with constraints on the relationships provided by the laws of thermodynamics. The result is derivation of the Helmholtz free energy function which is a sum of the free energies for elastic strain, plastic strain, and damage, and a constitutive equation where all coefficients are equal to those for the initial elastic material. In addition, the model is applicable for all material types from orthotropic to isotropic and for a specific material system require only the development of the material dependent damage growth laws to complete the model. Although the resulting equations are similar to those assumed in previous damage mechanics research, this study lends credence via derived information to those previously assumed. |
