Summary:"Starting from the concept of deterioration, using the principle of critical energy and considering the nonlinear, power law, behavior of the sample, or of the mechanical structure, there were proposed relations for critical stresses in the case of: – uniaxial static loading with normal stress or with shear stress, or simultaneously with normal and shear stress; – uniaxial cyclic loading with one block of normal stress or one block of shear stress, as well as simultaneous with a block of normal stress and one block of shear stress, taking into account the deterioration due to crack. Failure criteria for cracked mechanical structures, uniaxial statically or cyclically loaded, have been developed. The critical stresses calculated for cracked samples compared with experimental results reported in literature, have shown good agreement between them. "
