A thermo-mechanical coupling model for predicting temperature and residual stress fields in selective laser melting

A thermo-mechanical coupling model for predicting temperature and residual stress fields in selective laser melting

A three-dimensional thermo-mechanical coupling model has been developed to simulate a single-layer multi-track selective laser melting process using the finite element method. The model takes into account the powder melting, vaporization, solidification, cooling and shrinkage processes. The model...
