在非局部理论框架下，研究了应变局部化现象模拟结果与所用非局部核函数的相关性。

Based on the nonlocal theory the correlation is studied between the nonlocal kernel function and the simulating result for the strain-localization behavior of brittle materials.

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。

Based on non-local theory, the damage variable is non-local variable and is dependent on local damage variable and its second spatial gradient.
