RISHot Tearing in Steels During Solidification: Experimental Characterization and Thermomechanical Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hot tearing is a major defect in castings or semifinished cast products. It corresponds to the opening of cracks in the mushy zone and, more precisely, in the areas with high fraction of ...
Finite Element Modeling of Powder Bed Fusion at Part Scale by a Super-Layer Deposition Method Based on Level Set and Mesh Adaptation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A super-layer deposition method is developed for 3D macroscopic finite element modeling of heat transfer at part scale during the powder bed fusion (PBF) process. The proposed super-layer strategy consists of the deposition ...
