Data repository for: Effective fracture toughness for heterogeneous materials accounting for the worst-case scenario

This dataset corresponds to the research article “Effective fracture toughness for heterogeneous materials accounting for the worst-case scenario” by Sen Liu and Yongxing Shen*. It comprises multiple .mat files, each filename includes the relevant section number from the paper along with key parameters of the associated numerical example. Each file includes data on the fracture energy, reaction forces and elastic energy throughout the crack nucleation and compelet fracture. Additionally, the phase field solution at complete fracture is also included.本数据集对应刘森（Sen Liu）与沈永兴（Yongxing Shen）* 发表的研究论文《考虑极端工况的非均质材料有效断裂韧性》（Effective fracture toughness for heterogeneous materials accounting for the worst-case scenario）。本数据集包含多个.mat格式文件，每个文件名均标注了论文对应的章节编号以及关联数值算例的关键参数。每个文件均收录了裂纹形核至完全断裂全过程中的断裂能、反力与弹性应变能数据，此外还包含完全断裂时刻的相场（phase field）解。
