Enhanced physics‐informed neural networks for hyperelasticity

open access: yesInternational Journal for Numerical Methods in Engineering, 2022
AbstractPhysics‐informed neural networks have gained growing interest. Specifically, they are used to solve partial differential equations governing several physical phenomena. However, physics‐informed neural network models suffer from several issues and can fail to provide accurate solutions in many scenarios. We discuss a few of these challenges and

fPINNs: Fractional Physics-Informed Neural Networks [PDF]

open access: yesSIAM Journal on Scientific Computing, 2019
Physics-informed neural networks (PINNs) are effective in solving integer-order partial differential equations (PDEs) based on scattered and noisy data. PINNs employ standard feedforward neural networks (NNs) with the PDEs explicitly encoded into the NN using automatic differentiation, while the sum of the mean-squared PDE-residuals and the mean ...

Discontinuity Computing Using Physics-Informed Neural Networks

open access: yesJournal of Scientific Computing, 2022
Simulating discontinuities is a long standing problem especially for shock waves with strong nonlinear feather. Despite being a promising method, the recently developed physics-informed neural network (PINN) is still weak for calculating discontinuities compared with traditional shock-capturing methods.
