The paper concerns application of the energy parameter, being a sum of the elastic and plastic strain energy density in the critical plane, for description of experimental data obtained from the fatigue tests of 35NCD16 steel, GGG40 and GGG60 cast irons subjected to constant amplitude cyclic tension-compression, torsion and variable-amplitude tension-compression, torsion and combined tension with torsion. It has been shown that the parameter of specific work of selected stress on selected strains in the critical plane is an efficient parameter expressing the fatigue life of analysed materials under the considered kinds of loading. The critical plane is the plane where the parameter of normal strain energy density reaches its maximum.
