AN ESTIMATION OF FATIGUE LIFE UNDER GENERAL STRESS

pages 9 - +7p., full text
The paper deals with an old problem of praxis. Structures, in general, are exposed to random excitations, which generate normal and torsional stresses. While an estimation of fatigue life is rather well known for uniaxial stress, quite different situation holds for combined random stress. A new approach to the title problem is described lower. It is based on cumulation of stress energy density in peaks of a complex damaging stress.
