Construction of the Equivalent Plastic Strain Increment

Studies in Applied Mathematics, 1972
Strain hardening plastic deformation of a material possessing a yield locus (f(σij)) which may be written as a homogeneous function of the stress components (σij), and which obeys the classical associated flow rule for metals (e.g. Bishop and Hill, 1951) is considered. The material may be anisotropic and may display plastic dilatation.

Equivalent Strains in Severe Plastic Deformation

Advanced Engineering Materials, 2003
AbstractThe concept of equivalent plastic strain is discussed. Definitions may be based on kinematic arguments (like change of geometry) or on equivalence of plastic work. Complications arise when strain is accumulated in increments with variable strain path.

Simplified models for residual stresses and equivalent plastic strains in cold-formed steel elliptical hollow sections

Thin-Walled Structures, 2020
Abstract The manufacturing process of cold-formed steel members induces cold work which has a significant effect on their structural performance. In order to assess this cold-working effect, residual stresses and equivalent plastic strains need to be quantified.

Experimental Relationship Between Equivalent Plastic Strain and Constraint for Crack Initiation

, 1993
The applicability of fracture mechanics data generated from standard fracture toughness specimens in predicting structural integrity is often a concern. For elastic-plastic conditions, a second parameter identified as “constraint” (hydrostatic stress divided by the equivalent stress) is being used to link different specimen/flaw configurations, thus ...

Investigating fretting wear mechanisms in Ti-6Al-4V: insights from residual stress and equivalent plastic strain analysis

Industrial Lubrication and Tribology
Purpose The study delves into the influence of wear cycles on these parameters. The purpose of this paper is to identify characteristic patterns of σRS and εPEEQ that discern varying wear situations, thereby contributing to the enrichment of wear theory.
