The novel method of representative crack elements, recently developed in the context of phase-field fracture, is adopted to the eigenfracture method. It is shown, that in contrast to previous eigenerosion formulations, the predicted crack deformations fulfil the constraint in the proof of -convergence. Unphysical predictions for crack deformations of previous eigenerosion models are shown for two elastic applications and are compared to the results of the novel approach as well as those of a discrete crack and a phase-field fracture model.

代表性裂纹单元的概念应用于特征断裂

特征断裂方法采用了最近在相场断裂背景下开发的代表性裂纹单元的新方法。结果表明，与之前的特征侵蚀公式相比，预测的裂纹变形满足收敛证明中的约束。显示了两种弹性应用中先前特征侵蚀模型对裂纹变形的非物理预测，并将其与新方法以及离散裂纹和相场断裂模型的结果进行了比较。
