English(EN) A Gaussian Process State Space Formulation for Materials Constitutive Modeling: Application to Quasi-brittle Materials

新的高斯过程模型增强了材料本构建模

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-28 04:00

研究人员开发了一种新颖的高斯过程状态空间模型（GP-SSM），以改进历史相关材料的本构建模。这一新框架用灵活的GP回归取代了传统的固定函数形式，并直接从可观察的应力-应变历史中学习潜在状态变量，自然地融入了不确定性量化。GP-SSM被应用于三轴压缩下的准脆性材料，成功地重现了复杂的行为和结构响应，并已导出用于Abaqus/Explicit。 AI

影响这项研究引入了一种更灵活、更具不确定性感知能力的材料建模方法，有望改进工程和计算科学中的模拟。

高斯过程状态空间模型在材料本构建模中的应用：以准脆性材料为例

arXiv:2610.33175v1 Announce Type: cross Abstract: Constitutive models for history-dependent, path-dependent materials typically encode this dependence in prescribed functional forms through internal variables such as damage or plastic strain that are phenomenological, model-depen…
