PACCAR

Validated Material Model with Damage

Paccar Technical Center currently does not have validated material model with damage. With limited requirements for crash/impact analysis in truck industry and a focus more towards durability analysis, there was no urgent need for material model validation with damage associated with it. However, with Paccar's development on the Battery electric vehicle and the requirement associated with impact analysis, the need for validated material model with failure has become utmost importance in order to provide good prediction on impact scenarios. This student team worked to create a test set-up for casting material (maybe one of PACCAR's casting components) with failure (coupon testing) to gather all the relevant data for material model development. This student team also worked to develop the material model with damage created, verified, and validated by test data.
