Abstract This work aims to introduce an alternative technique to address the fracture process of brittle and quasi-brittle materials under the Material Point Method (MPM) framework. With this purpose the eigensoftening algorithm, developed originally for the Optimal Transportation Meshfree (OTM) approximation scheme, is extended to the MPM to present a suitable alternative to the existing fracture algorithms developed for such a methodology. The good fitting in the predictions made by the eigensoftening algorithm against both analytical and experimental results proves the excellent performance of the method when challenging applications are to model.

局部最大熵材料点法应用于准脆性断裂

摘要 本工作旨在介绍一种替代技术，以解决材料点法 (MPM) 框架下脆性和准脆性材料的断裂过程。为此，最初为最佳运输无网格 (OTM) 近似方案开发的本征软化算法被扩展到 MPM，以呈现为这种方法开发的现有断裂算法的合适替代方案。特征软化算法的预测与分析和实验结果的良好拟合证明了该方法在具有挑战性的应用程序建模时的出色性能。
