Structures submitted to variable loads and temperature fields may enter a regime of ratcheting, where strains and, hence, structural deflections increase cycle by cycle. It is important to demonstrate that ratcheting is avoided. This happens if the structure remains entirely in the elastic regime. However, for more severe loadings, plastic deformations occur and the analyst must then demonstrate that the structure shakes down or adapts. Shakedown may be elastic (if after a transient period all strain variations become elastic) or plastic (when alternating plasticity occurs). This report addresses plastic shakedown. The problem is treated from the theoretical point of view and also from the numerical and software point of view.
