混凝土各向异性损伤模型

Anisotropic Damage Model for Concrete

在能量等价假设的基础上建立了混凝土的各向异性损伤本构方程。损伤演变由损伤强化条件决定，当损伤强化达到临界值时，混凝土发生破坏。本模型能较好地描述混凝土的单侧受力性能。

In this paper an anisotropic damage model is developed based on the principle of energy equivalence. The evolution of damage is determined by damage hardening condition, failure occurs when the hardening of damage reaches its critical value. The unilateral behaviour of concrete can be described appropriately by the proposed model.
