Investigation on multi-layer selective inhibition sintering process using finite element analysis

Analysis of geometrical defects in overhang fabrications in electron beam melting based on thermomechanical simulations and experimental validations

“…The selection of one or another technique mainly depends on the scale of the study, the physical phenomena to be modeled, the expected accuracy and the available computing resources. In our case, we use thermo-elastoplastic analysis to simulate the geometrical defects coupled to the "element birth technique" [21], [24], [29]- [31] for the addition of new layers in both thermal and mechanical models. In this technique, the mesh of the complete geometry is created and all elements are initially deactivated.…”
