Three factors govern adiabatic shear localization: strain hardening (or softening), strain-rate
hardening, and thermal softening. It is typically associated with large shear strains (> 1), high …

During the last few decades, there has been significant progress in developing industry-
driven predictive models for machining operations. This paper presents the state-of-the-art in …

Detrimental subsurface tensile residual stresses occur in laser powder bed fusion (LPBF)
due to significant temperature gradients during the process. Besides heat treatments, laser …

In literature, five different sets of work material constants used in the Johnson–Cook's (J–C)
constitutive equation are implemented in a numerical model to describe the behaviour of …

Titanium alloys are known as difficult-to-machine materials, especially at higher cutting
speeds, due to their several inherent properties and their high reactivity with cutting tools …

Tool-edge geometry has significant effects on the cutting process, as it affects cutting forces,
stresses, temperatures, deformation zone, and surface integrity. An Arbitrary-Lagrangian …

A parameterized identification method is proposed that uses the material Johnson–Cook
constitutive model to improve the accuracy of finite element simulations in cutting processes …

Finite Element (FE) modeling of machining processes has received growing attention over
the last two decades. Since machining processes operate at severe deformation conditions …

Additive manufacturing (AM) is known to generate large magnitudes of residual stresses
(RS) within builds due to steep and localized thermal gradients. In the current state of …

This research proposes an innovative method to study the machined surface integrity and
the variation of cutting mechanisms during a continuous rapid transition between different …
