新型本构状态空间模型增强塑性模拟

研究人员开发了一种新的本构状态空间(CSS)模型,用于模拟材料中依赖路径的塑性。该框架将状态空间动力学重新表述为增量本构算子,将应变增量分解为幅度和方向,以改进并行训练并降低对离散化应变路径的敏感性。CSS模型在预测精度上与现有的最小状态单元(MSC)架构相当或更优,对于不可压缩材料具有显著更低的验证损失,并且对变化的应变路径分辨率具有更强的鲁棒性。此外,CSS训练速度更快,所需数据点更少即可达到高精度,并揭示了与物理本构模型一致的潜在结构。 AI

影响 这一新框架为材料科学中数据驱动的本构建模提供了一种更高效、更鲁棒的计算方法,有望加速依赖塑性模拟的领域的研究和开发。
