Hyperelastic material modelling and validation using LS-DYNA

What will you do in this project?

You will be performing a tensile test on a dogbone specimen to validate the hyper-elastic material model. You will do the following in this project,

• Input experimental stress-strain data through hyper-elastic material card
• Set-up a tensile test case study by applying required boundary conditions in LS-PrePost
• Evaluate the fitted curves for various number of constants for the hyper-elastic material model
• Tensile test simulation using the obtained constants and result extraction
  
• Analyse and compare the stress-strain results with the given data

Benefits of this Project

Understand how to perform a tensile test to calculate the Mooney Rivlin and Ogden material parameters and compare it with the given stress-strain data. Learn how to use hyper-elastic material card and give particular inputs for simulation. Study and understand conversions from engineering stress-strain to true stress-strain and terms like stretch ratio and extension. Finally, understand curve fitting and compare the simulation and given stress-strain data.
