Experimental investigations in the field of low-cycle compression fatigue at a relatively high upper loading have revealed a drop in life time under certain loading conditions relevant for off-shore con- structions. The prevailing mechanism leading to such premature fracture was cracking due to stress release. It occurred at a fre- quency of 17 .5 Hz and at maximum stress amplitude. A structural study based on a stereological analysis of the damage structure at the end of testing offered insight into the damage evolution process under these conditions.
