Micro-scaled progressive sheet metal forming is a promising process for producing bulk microparts, given its advantages of high efficiency and low cost. To enhance quality efficiency, it important to have an in-depth understanding the mechanism model fracture behavior accurately. However, prediction formation in materials at micro-scale has not yet been well explored, thus current knowledge suf...

A ductile damage model, which fully couples classical void growth at high stress triaxiality and Coulomb model the slip system scale low triaxiality, was applied for sheet specimens in an anisotropic aluminum alloy under non-proportional load path changes. The combines resolved normal shear stresses each plane directions. Reduced Texture Methodology (RTM) used to provide computational efficienc...

Two primary variables that impact failure behavior of ductile metals are defects and stress state. These factors especially critical in additively manufactured materials, as components made by additive manufacturing (AM) can have complex shapes result the material being subjected to multiaxial stresses under load, these materials may also contain internal porosity due AM processing. This study ...
