I would like to seek comments on : Room temperature stress relaxation and governing mechanisms that contribute to the plasticity that occurs during this process. As, most of the available work on relaxation is done at elevated temperatures.

I have also attach papers by Prof Hart and Prof Krempl that did throw some light on this particular subject.

tension/compression moduli

Hello all

I am trying to model a composite material with different tension and compression modulus (elastic analysis). Does anyone know how to do it ??

Thanks for help.

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.

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.
