This repository provides numerical examples of physics-informed neural network-based computational solid mechanics framework.
Physics-informed neural network (PINN) has recently gained increasing interest in computational mechanics.
This work aims to help the researchers who are interested in the PINN-based solid mechanics solver to have a clear insight into this emerging area.
Numerical examples include:
- 1D stretching plate problem (implemented by collocation and energy-based loss functions)
- 2D in-plain stretching plate problem (implemented by collocation loss function)
- 2D in-plain stretching plate problem (implemented by energy-based loss function)
- 3D streching cube problem (implemented by collocation loss function)
