Al alloys

 My last two posts on this series

Part- 1 (node/9016) and

Part- 2 (node/9073)

were mainly focussed on the tension–torsion (σ11–√3σ₁₂) stress space. This paper will be the final post on this series and will focus mainly on the behavior of  both of these alloys under tension–tension (σ₁₁–σ₂₂)space and conclude this ongoing research.

Abstract.

Continuing on the work from the previous thread posted on

node/9016

It is essential to know the amount of springback for a given forming process, so that the process or the design of the tool can be modified to obtain the desired product shape. This requires a comprehensive understanding of loading and unloading processes, and determination of elastic constants with finite plastic deformation which, in turn, require precise determination of subsequent yield surfaces.
