Polyconvex neural-network surrogates with learned paired directional features for anisotropic hyperelastic homogenization

Approximating the effective anisotropic hyperelastic response of a representative volume element (RVE) requires constitutive expressiveness, mechanical consistency, and computational efficiency. This work develops a polyconvex physics-augmented neural network (PANN) construction based on paired directional features who...
