WINO: A Weak-Form Physics Informed Neural Operator for Hyperelasticity on Variable Domains

Read the original on arXiv Machine Learning →

arXiv:2605. 24651v2 Announce Type: replace-cross Abstract: We propose a Weak-form Physics-Informed Neural Operator (WINO), a data-free framework that combines the efficiency of neural operators with the geometric flexibility of the $\varphi$-finite element method ($\varphi$-FEM).
