Plastic deformation and hardening characteristics of the staggered zone under high in-situ stress unloading conditions

Rock and Soil Mechanics, 2022
To clarify the plastic law and hardening characteristics of deformation and failure of staggered zone under high in-situ stress unloading conditions with excavation in underground engineering, a series of triaxial tests under different confining ...

Investigation of microstructure and mechanical properties of copper shell produced by shear spinning in different rotation directions

Materials Research Express, 2021
In this study, the effect of alteration in the direction of forming during the shear spinning of C11000 copper metal on mechanical properties, microstructure, texture, and anisotropy was investigated. Shear spinning causes the grains stretching along the

Determination of Local Stresses and Strains within the Notch Strain Approach: The Efficient and Accurate Calculation of Notch Root Strains Using Finite Element Analysis

Applied Sciences, 2021
For the service life estimation of metallic components under cyclic loading according to strain-based approaches, a simulation of the elastic-plastic stress–strain path at the point of interest is necessary.

Yield stress after double strain-path change [PDF]

, 2000
Two different types of complex loading paths, with three strain paths (rolling-rolling-tension), were carried on a polycrystalline copper sheet. The first and second paths in rolling were performed perpendicular to each other.

Effect of Strain Path on Retained Austenite Transformation Rates and Material Ductility in Transformation-Induced Plasticity-Assisted Advanced High-Strength Steel

Journal of Manufacturing and Materials Processing
TBF 1180 steel was plastically deformed under different strain paths in order to study both the ductility and RA transformation rates. Specimens were prepared from a 1 mm thick sheet and then tested incrementally under uniaxial tension, plane-strain ...

In-situ study of rules of nanostructure evolution, severe plastic deformations, and friction under high pressure

Materials Research Letters, 2023
Severe plastic deformations under high pressure are used to produce nanostructured materials but were studied ex-situ. Rough diamond anvils are introduced to reach maximum friction equal to yield strength in shear and the first in-situ study of the ...

A Simple Method for Triaxial Strain Path Testing

Soils and Foundations, 1996
ABSTRACT A new, simple method is presented for testing triaxial soil samples along constant strain increment ratio paths. In this method, by adjusting the ratio of the diameter of the top cap at the free end to that of the soil sample before a test, strain path testing with a constant strain increment ratio (the ratio of the radial strain increment ...

The moment of inertia method to calculate equivalent ranges in non-proportional tension–torsion histories

Journal of Materials Research and Technology, 2015
A critical issue in multiaxial damage calculation in non-proportional (NP) histories is to find the equivalent stress or strain ranges and mean components associated with each rainflow-counted cycle of the stress (or strain) path.
