We propose a formulation for tracking general crack paths in elastodamaging materials without mesh adaptivity and broadening of the damage band. The idea is to treat in a unified way both the damaging process and the development of displacement discontinuities by means of the regularized finite element method. With respect to previous authors’ contributions, a novel damage evolution law and an original crack tracking framework are proposed. We face the issue of mesh objectivity through several two-dimensional tests, obtaining smooth crack paths and reliable structural results.

通过规则化扩展有限元方法的网格无关框架，用于弹性损伤材料中的裂纹跟踪

我们提出了一种公式，用于跟踪弹性破坏材料中的一般裂纹路径，而无需网格适应性和破坏带的扩展。想法是通过正则化有限元方法以统一的方式处理破坏过程和位移不连续性的发展。关于以前的作者的贡献，提出了一种新颖的损伤演化规律和原始的裂纹跟踪框架。通过几个二维测试，我们面临着网格客观性的问题，获得了平滑的裂纹路径和可靠的结构结果。
