Physics-informed neural network-based computational solid mechanics

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)

Information regarding the numerical examples, please refer to our paper.

Enviornmental settings
