Abstract— Mechanical analyses of structures, to be efficient, must incorporate materials behaviour data. Among the mechanisms liable to cause collapse, progressive distorsion (or ratcheting) has been the subject of only a few basic experiments, most of the investigations being theoretical. In order to get meaningful results to characterize materials behaviour, an experimental study on ratcheting of austenitic steels has been undertaken at the C.E.A.This paper gives the first results of tests at room temperature on thin tubes of 304 L steel submitted to an axial constant stress (primary stress) to which is added a cyclic shearing strain (secondary stress). The tests cover a large combination of the two loading modes. The main results consist of curves of cumulative iso-deformation in the primary and secondary stress field (Bree type diagrams). Results are given for plastic deformations ranging from 0·1 to 2·5% up to N= 100 cycles.
