This paper proposes a yield function to model sheet metal strength between shear and
plane strain tension. The function is expressed as an equation of the three stress invariants …

Failure in lightweight metal forming is a big challenge currently and prevents their widely
application in weight reduction of automobile and aerospace structures. A stress-based …

Sheet metal experiences various stress states during plastic deformation, including uniaxial
compression, shear, uniaxial, plane strain and equibiaxial tension, but the existing yield …

In the present study, experimental and theoretical analyses were performed to predict the
