A mathematical representation of the multiaxial Bauschinger effect

The above title and authorship belong to an internal Company Report that was issued 1966 1 and is still often referred to, but it has never been published in the open. The report is reproduced in full below as a paper, but Materials at High has first taken the opportunity to explore the background to what is by many in the field as a classic work. of original 1966 CEGB internal research report in Materials at High Temperatures Vol. 24, No. 1 pp. 1-26 Inelastic stress analysis would be totally impractical without simplified mathematical of the behaviour of structural materials. Naturally these should be as accurate possible; they should, for instance, display a Bauschinger effect in timeindependent. attempts to do this do not appear to be wholly adequate and a new material model is proposed here. On the available evidence it appears to represent more accurately than previous models. extension of the proposed behaviour model to include time dependent effects is briefly.
