Evolution of plastic deformation behavior upon strain-path changes in an A6022-T4 Al alloy sheet [PDF]

open access: yesInternational Journal of Plasticity, 2021
The plastic deformation behavior under various strain-path changes in an A6022-T4 Al alloy sheet was studied, focusing on the evolution of the direction of the plastic strain rate θ and the stress ratio φ after abrupt strain-path changes.

Development of a novel testing methodology for in-situ microstructural characterisation during continuous strain path change [PDF]

open access: yesMaterials Characterization, 2022
Strain path transition is a common phenomenon during continuous stamping operations of sheet metal and can potentially alter the forming limit of the material.

Effect of continuous strain path changes on forming limit strains of DP600

open access: yesStrain, 2019
International audienceThe strain path may change in actual sheet metal forming processes, so the determination of formability of sheet metal should consider the non-linear strain path.

Strain path and surface roughness

Mechanics of Materials, 1992
Abstract The strain path effect on the roughening of free surfaces of copper alloy is experimentally studied. It is observed that surface roughness is dependent of strain paths for a given effective strain level. However, if no reverse yielding occurs, this effect is not obvious.

Stress-strain behaviour at finite strains for various strain paths in polyethylene

Journal of Materials Science, 1992
In order to provide new experimental facts required for constructing a non-linear constitutive equation for crystalline polymers, some tests were conducted by the use of polyethylene (PE) under various strain histories such as tension, torsion, tension-torsion proportional strain path, tension-torsion cruciform strain path, tension-torsion circular ...

Strain Path Method

Journal of Geotechnical Engineering, 1985
The Strain Path Method provides an integrated and systematic framework for elucidating and predicting pile foundation behavior, interpreting in situ tests, assessing sampling disturbance effects and, in general, approaching “deep geotechnical problems” in a consistent and rational manner.
