Abstract

The component's damage is a common problem during tailored forming. It occurs frequently in forging and quenching processes. Traditional damage models are struggling to accurately and efficiently simulate large-scale three-dimensional models with a great number of degrees of freedoms. This article provides a new gradient-enhanced damage model based on the extended Hamilton principle. It significantly reduces the computation time while ensuring mesh-independence. This method is applied to predict the damage evolution during two abovementioned processes.
