Within solution of the grant GAČR 101/09/0904 of ČVUT praha and ÚT AVČR, v.v.i., we tried to find a new approach to solve the above issue which would be based on finding links between spectral properties of individual loading process components and the actual life related to the number of blocks of random loading process to fracture.The paper presents some pieces of knowledge which were acquired within an extensive experimental program on tube specimens with a cross hole and subjected to a ccombination of random processes in tension-pressure and torsion.
