Investigation on the Ratcheting-Effect of fusion reactor first wall under cyclic thermal and mechanical loading
In order to study the boundary conditions for the occurrence of ratcheting, a testing rig has been erected at KFA. In this rig small scale mock ups of the first wall, concerning the design of ITER-CDA stage, have been tested under conditions similar to those expected during the operation of ITER. In addition to the experimental work, theoretical analysis of the ratcheting phenomenon was carried out. Using simplified beam models, so-called BREE diagrams were developed to characterise the structural behaviour as a function of the applied primary and secondary stresses.
