摘要

En 中文

断裂是一种基本的物理现象，具有跨多领域的广泛相关性，涉及基础设施完整性、航空航天耐久性、储层生产和地震事件等领域。我们介绍了一个由两种数值求解器生成的模拟断裂演化和材料失效的多样化数据集：相场法和有限元-离散元耦合方法（FDEM）。这些求解器在公式、物理保真度和计算效率方面存在差异。数据集包含五种材料：PBX、各向异性页岩、钨、铝和钢。对于每种材料，相场模拟覆盖40万个案例：20万个在单轴拉伸下，20万个在双轴拉伸下。计算成本较高的FDEM模拟包括9万个案例，均匀分布在PBX、页岩和钨的单轴加载条件下。所有模拟均以随机的初始断裂模式开始。每个条目包含时间数据，捕捉断裂传播动力学。该综合数据集旨在支持基础或代理机器学习方法在预测材料失效方面的开发。虽然本文未引入此类模型，但该数据集为这些领域未来研究和创新奠定了坚实基础。
