A few of you might find this interesting. We indented a disk of aluminum in order to make a specimen with residual stress. The loading was axisymmetric. The aluminum had plastic anisotropy of about 10%. Because of that mild anisotropy, the residual stresses were anisotropic by about 40% and the residual strains were anisotropic by 100%.

The paper is free until July 31 at https://authors.elsevier.com/a/1VCA54kE0BEFT

Dear colleagues,

It is common practice when solving boundary value problems to split the solution into a symmetric and an antisymmetric part to temporarily reduce the number of variables and the mathematical administration. As soon as the symmetric problem is solved, the antisymmetric problem, or vice versa, is almost solving itself. Any problem can be split into a symmetric and an antisymmetric part which is a relief for anyone who analyses mixed cases.

We are looking for a PhD and postdoc researcher in thermographic inspection of composites, in the context of NDT (NonDestructive Testing) and defect detection.
