Modeling sheet metal forming operations requires understanding of the plastic behavior of
sheet alloys along non-proportional strain paths. Measurement of hardening under reversed …

Nano metallic laminates (NMLs) exhibit exceptional strengths. The viability of NMLs as
structural materials, however, is also conditioned on their ductility and work-hardenability …

It is essential to model the Bauschinger effect correctly for sheet metal forming process
simulation and subsequent springback prediction when material points are subjected to …

Springback angles and anticlastic curvatures reported for a series of draw-bend tests have
been analyzed in detail using a new anisotropic hardening model, four common sheet metal …

Attributed to their superior properties over the conventional alloys, high-entropy alloys
(HEAs) have attracted considerable interest. One of HEAs' attractive properties is their high …

Numerical models of structural components that deteriorate primarily due to geometric
instabilities under multiaxis cyclic loading are sensitive to both the assumed geometric …

Continuum and microstructural theories of the Bauschinger effect are reviewed in relation to
present understanding of the role of internal stresses in work hardening. Influences of …

The Bauschinger effect in thin sputter-deposited Al and Cu films is studied by isothermally
deforming the films alternately in tension and compression. Passivated films exhibit an …

Springback prediction is an important issue for the sheet metal forming industry. Most sheet
metal elements undergo a complicated cyclical deformation history during the forming …

The nature of strain hardening in glassy polymers is investigated by studying the mechanical
response of oriented polycarbonate in uniaxial extension and compression. The yield stress …
