A COMPARATIVE STUDY OF VARIOUS MODELS OF EQUIVALENT PLASTIC STRAIN TO FRACTURE

Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2023
For more then half a centre just the same approach to the simulation of the ductile crack formation was developed independently by the scientific communities of foreign and native researchers. The importance at these studies drastically increased. A set

Ductile fracture locus identification using mesoscale critical equivalent plastic strain [PDF]

Fatigue & Fracture of Engineering Materials & Structures, 2021
AbstractThe ductile performance of high strength steel (HSS) from different steel grades, producers, manufacturing processes varies a lot. It is also difficult to conduct all kinds of reliable experiments to generate different stress status through different initial specimen geometries or by applying different load combinations in the civil engineering

Constitutive Model for Equivalent Stress-Plastic Strain Curves Including Full-Range Strain Hardening Behavior of High-Strength Steel at Elevated Temperatures [PDF]

Materials, 2022
High-strength steel has been increasingly applied to engineering structures and inevitably faces fire risks. The equivalent stress-plastic strain (σeq− εeqp) curves of steel at elevated temperatures are indispensable if a refined finite element model is used to investigate the response of steel members and structures under fire.

Equivalent plastic strain gradient enhancement of single crystal plasticity: theory and numerics [PDF]

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
We propose a visco-plastic strain gradient plasticity theory for single crystals. The gradient enhancement is based on an equivalent plastic strain measure. Two physically equivalent variational settings for the problem are discussed: a direct formulation and an alternative version with an additional micromorphic-like field variable, which is coupled ...

Diameter ratio and friction coefficient effect on equivalent plastic strain (PEEQ) during contact between two brass solids [PDF]

Cogent Engineering, 2023
AbstractThe study of contact mechanics is rapidly expanding in scope and importance. However, most studies of spherical do not spend significant time comprehensively analysing PEEQ, especially in the effect of friction coefficient and diameter ratio. This study aims to introduce comprehensive research examining diameter ratio and friction coefficient ...

A Study on the Equivalent Stress and the Equivalent Plastic Strain Rate : Theory of Anisotropic Plasticity Based on the Maximum Shear Stress Hypothesis

Bulletin of JSME, 1972
A conception of the equivalent stress and the equivalent strain rate can be used for comparison of the yield surfaces or the stress-strain diagrams of the materials deformed plastically under combined stresses. There is a close relationship between formulating the equivalent strain rate and selecting the type of the equivalent stress.

Study on the definition of equivalent plastic strain under non-associated flow rule for finite element formulation [PDF]

International Journal of Plasticity, 2014
Abstract As opposed to associated flow rule (AFR) in which yield function and plastic potential are equal, the different definitions for them is an inherent characteristic of non-associated flow rule (non-AFR). This imposes a specific relation (but not equality) between equivalent plastic strain and plastic compliance factor.
