脆(弹)性损伤本构的统一模型

A Unified Damage Constitutive Model for Elasticity

基于连续介质损伤力学,本文提出了脆(弹)性损伤本构的统一模型。该模型从能量的角度来定义各向异性损伤张量,并采用能量等效假设来推导各向异性脆(弹)性损伤的本构方程。新模型可退化到Lemaitre的各向同性损伤模型。

Based on continuum damage mechanics, a unified damage constitutive model for elasicity is proposed. An anisotropic damage tensor is defined from the view of energy and constitutive equations of anisotropie damage for elasticity are derived using the hypothesis of energy equivalence. The new model can be degenerated to Lemaitre's model for isotropic damage.
