Based on non-localtheory, the damage variable is non-local variable and is dependent on local damage variable and its second spatial gradient.
基于非局部理论，将损伤变量作为非局部变量，它与局部损伤变量及其二阶梯度有关。

The present theory can be applied to nonlinear geometrical and nonlinear physical crack problems for simple materials with internal variables or fading memory, within the framework of localtheory.
本理论可应用于具有内变量或衰退记忆的简单物质在局部理论范围内的几何非线性和物理非线性裂纹问题。
