Abstract Dynamic Strain Ageing (DSA) has reached widespread acceptance since its
proposal in the 1940's as the mechanism behind the Portevin-Le Chatelier effect in ferritic …

Numerical simulations have become essential in engineering and manufacturing processes
involving plasticity. The reliability and effectiveness of the simulations depend strongly on …

The objective of the present paper is to develop a thermodynamically consistent coupled
damage-plasticity model at large deformations, which accounts for damage anisotropy …

In this paper, the multi-scale strain characteristics of AA2219 alloy friction stir welded joints
deformation at cryogenic temperature were analyzed quantitatively. The macro strain …

Biaxial testing technology enables the comprehensive study of sheet-forming performance
and has great potential developmental and commercial value. This work is a review of …

Under certain strain paths (eg, balanced biaxial) and during some forming processes (eg,
incremental forming, micro forming), sheet metals may deform and fail without forming a …

Background Evaluation of material properties under biaxial loading is a cumbersome
process. Biaxial mechanical properties using the planar biaxial testing technique is a very …

In microforming process, the metal foil is often deformed under complex stress states and
meanwhile affected by the scale effect. To explore the size effect on the yield behavior of …

The assessment of mechanical properties of metal foil under complicated stress states
poses a considerable challenge, requiring the development of new testing methods and the …

Background: For the standard ISO 16842 cruciform test specimen, stresses obtained from
the gauge area are far below the ultimate tensile strength due to high stress concentrations …
