RISA Finite Element Study of Large Strain Extrusion Machining Using Modified Zerilli–Armstrong Constitutive Relation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this work is to study the performance of modified Zerilli–Armstrong constitutive relation proposed in our previous study for the finite element modeling of a severe plastic deformation technique called ...
Effect of Process Parameters on Texture in Quasi-Isotropic IN718 Processed by Laser Powder Bed Fusion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study attempts to elucidate the quasi-isotropic behavior observed in laser-based powder bed fusion of Inconel 718 (IN718) alloy. This effort emphasizes the effect of laser process parameters on crystal orientation and ...
Influence of Inhomogeneous Deformation on Tensile Behavior of Sheets Processed Through Constrained Groove Pressing
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Constrained groove pressing (CGP) is a severe plastic deformation technique to produce the ultra-fine grained sheet. The inhomogeneous strain distribution and geometry variation induce differential mechanical properties ...
