基于有限元方法和材料劣化规则，提出了一种新型的破坏生长模型，改进了以往模型的不足，并在此基础上对强度的尺寸效应进行了分析，获得了预期的结果。
A noval frature growing model based on FEM and degrading rules of materials was proposed,and many disadvantages of existing model were improved with the new modal , dimensional problem was analysed and satisfactory results was gained.
