WINO: A Weak-Form Physics Informed Neural Operator for Hyperelasticity on Variable Domains
Bokai Zhu, Yizheng Wang, Qinghui Zhang +1
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 -fin…

Condensed Generalized Finite Element Method (CGFEM)
Qinghui Zhang, Cu Cui
Generalized or extended finite element methods (GFEM/XFEM) are in general badly conditioned and have numerous additional degrees of freedom (DOF) compared with the FEM because of i…
