Guided industry project
Elasto-plastic material modelling and validation using LS-DYNA
In this project, you will learn how to validate the elasto-plastic material model with the given stress-strain data. You will learn the extraction and cleaning of the stress-strain data point from the given curve. Then you will study how to evaluate the hardening curve and give material parameters input to the LS-DYNA software. Finally, you will understand how to extract the stress-strain results from the simulation and compare it with the given data.
