The present paper studies the effect of creating a fillet on fretting fatigue strength of an axle, using different multiaxial fatigue criteria and fretting fatigue damage parameter. Finite element method is applied to obtain stress and strain in the axle and the results obtained from modeling are compared with the experimental test data available in literature. The results show that fretting fa...
this paper presents an experimental study the influence of wave parameter on the damage of reshaping seawall, model tests have been performed in several water level conditions. the experiments of physical modeling of this research have been done in the flume of the soil conservation and watershed management research institute (scwmri). the waves applied to the structure model are irregular and ...

Life assessment on the base of grain boundary creep cavitation of 1%Cr - 0.5%Mo low alloy steel has been discussed in this paper. Since microstructural degradation is one of the most important mechanisms that affects creep life, it is necessary to assess microstructural damage in order to estimate the life. Microstructural damage within the grain boundaries is a continuous phenomena starting fr...
this work is an attempt towards employing ductile damage criterion and finite elementsimulations for prediction of fracture initiation and evolution in deep drawing of copper/stainlesssteel clad sheets. the material mechanical properties and ductile damage parameters weredetermined through standard and notched tensile tests. the effect of some important processparameters on damage evolution wer...
In this article, the isothermal low-cycle fatigue continuum damage in the engine piston aluminum alloy has been evaluated at different temperatures. For this objective, experimental data of low-cycle fatigue tests on standard specimens were used at 280, 350 and 425°C. Based on the continuum damage mechanics method, the fatigue damage was calculated during cyclic loading. Obtained results, inclu...
