The contribution deals with a complicated problem of fatigue damage of structure parts, which are loaded by a combination of random forces in tension-pressure and moments in torque. An attempt for estimating the total damage is made. It is basedon an application of a virtual damaging stress. The damage is evaluated by meansof the hypothesesof Palmgren-Miner and Corten-Dolan, which are appliedto a rain -flow-like sequence of a resulting stress.
