Role of Initial Crack Tip Shape, Plastic Compressibility and Strain Softening on Near-Tip Stress-Strain State in Fatigue Cracks during Simulation of a Finite Deformation based Elastic-Viscoplastic Constitutive Model

open access: yesMedžiagotyra, 2022
This paper deals with the effect of initial crack tip shape, plastic compressibility, and strain softening on near-tip stress-strain fields for a mode I crack subjected to fatigue loading under plane strain and small scale yielding. A finite strain-based

Strain Hardening at Large Strains [PDF]

open access: yes, 1989
The strain hardening properties of various fcc metals have been investigated at large strains by means of torsion tests of short thin-walled cylinders. The results show that Stage IV occurs in all cases provided that a low enough test temperature is used; it is a nearly constant hardening rate of 2.10/sup /minus/4/ G in terms of resolved flow stress ...

Strain Hardening of Polymer Glasses: Entanglements, Energetics, and Plasticity [PDF]

open access: yes, 2008
Simulations are used to examine the microscopic origins of strain hardening in polymer glasses. While stress-strain curves for a wide range of temperature can be fit to the functional form predicted by entropic network models, many other results are ...

Deforming glassy polystyrene: Influence of pressure, thermal history, and deformation mode on yielding and hardening [PDF]

open access: yes, 2009
The toughness of a polymer glass is determined by the interplay of yielding, strain softening, and strain hardening. Molecular-dynamics simulations of a typical polymer glass, atactic polystyrene, under the influence of active deformation have been ...

Evaluation on Flexibility of Phenomenological Hardening Law for Automotive Sheet Metals

open access: yesMetals, 2022
Constitutive modeling of sheet metals involves building a system of equations governing the material behavior under multi-axial stress states. In general, these equations require a hardening law that describes the stress-strain relationship.
