Abstract: A concept of cumulative damage is developed for an evaluation of the damage incurred under creep loading at high temperature. The damage is essentially stress-dependent and is a non-linear ...

Abstract: A recently suggested procedure for estimating the life of a material subjected to fatigue-creep loading is applied to analyze the behavior of Type 304 stainless steel on the basis of the ...

Abstract: Low-cycle fatigue tests on Ti 6-4 (Ti-6Al-4V) have been carried out at 260°C under strain-controlled conditions with constant strain amplitude and increasing multistep strain levels. The ...

Abstract: This paper describes a procedure that permits the calculation of the fatigue life over a wide range of temperatures and strain rates. The isothermal fatigue life is expressed in terms of the ...

Abstract: Under cyclic loading, the effect of stress raisers on the fatigue life depends upon several parameters, the most important being the stress concentration factor, the stress level, and the ...

Abstract: Crack growth behavior at room temperature and at 600°C of SS 304 plates with a central circular hole is studied using linear elastic and elastic-plastic fracture mechanics concepts. Due ...

Abstract: Large specimens of an ASTM E-373-58T steel were subjected to zero-tension cyclic loading, hence with nonzero mean stress, under a repeated programmed pattern of nine stress levels. With the ...

Abstract: A series of cumulative damage strain-controlled fatigue tests at 20°C has been carried out on a Type 304 stainless steel with two, three, and five strain levels, both in an increasing ...

Abstract: A phenomenological approach, already used for other materials, is applied for the prediction of the behavior of 316 stainless steel under fatigue, creep or combined fatigue-creep loadings. The ...
