"The analogy to cumulative increment of damage connected with the closing of hysteresis loops at uniaxial loading does not exist for general multiaxial loading - hysteresis loops do not come into being. Using of the alternative rain-flow methods in each points of structure and on a lot of planes with different geometrical normals is numerically unworkable. Therefore, it is necessary to find another way how to project the continual energy changes in the calculation of life time. The published results and our own results demonstrated the usability of general uniaxial loading spectral or probabilistic properties and multiaxial fatigue criteria for the estimations of life time. Hence, there is a possibility to use this procedure also for the cases of combined stochastic loading. The proposed research will be based on own experiments with the combination of tensile and torsion loadings with various shapes of power spectral densities (PSD) on smooth and notched specimens. Numerical procedures of the damage parameters on critical planes by stochastic process will be described. A method of life time prediction will be proposed for general combination of loading processes."@en . . "1"^^ . "1"^^ . . . . "2011-04-16+02:00"^^ .
