Plasticity Modelling of Titanium and Steel Alloys fabricated via Powder Bed Fusion and Material Extrusion: A Phenomenological Constitutive Approach

Abstract

This paper reviews examples of advanced, yet easy to employ, constitutive plasticity models for powder bed fusion (PBF) and material extrusion (MEX) alloys, such as Ti-6A-4V, maraging steel 300 and steel 316L. It intends to showcase a phenomenological constitutive approach that can be scaled up for the benefit of the design/redesign process and the sustainment of metallic structures and parts.

Keywords: powder bed fusion, material extrusion, additive manufacturing, plasticity
