摘要:The fatigue of materials is interpreted by the asymmetrical stress in dynamic process. The asymmetrical stress equation is used as the controlling equations. The fatigue is measured by the irreversible local rotation angular. For harmonic loading and step-loading, the fatigue form solution is obtained. Based on this result, the material life is calculated.

Abstract:The fatigue of materials is interpreted by the asymmetrical stress in dynamic process. The asymmetrical stress equation is used as the controlling equations. The fatigue is measured by the irreversible local rotation angular. For harmonic loading and step-loading, the fatigue form solution is obtained. Based on this result, the material life is calculated.
