Neural Network Solvers for Nonlinear ODEs: Benchmarking MLPs and B-Spline/Chebyshev KANs

Three neural networks are compared as solvers of nonlinear ordinary differential equations: a multilayer perceptron (MLP), a Kolmogorov-Arnold network (KAN) whose edges are B-splines, and a KAN whose edges are Chebyshev series. Each network is trained only on the residual of the equation and on its initial or boundary...

Decoupling deformation modes: a physically interpretable neural network for hyperelastic constitutive modeling

Hyperelastic constitutive models traditionally rely on a single global strain energy density function defined by deformation invariants. While this approach ensures thermodynamic consistency and mathematical simplicity, it implicitly forces a uniform energy landscape across all deformation modes. As demonstrated by...
