Understanding Prisoner VictimisationUsing damage mechanics a constitutive equation for fatigue damage accumulation has been developed which takes into account strain level effects. In this manner, damage evolution over the entire life may be predicted accurately. It is shown that good estimates of fatigue life may be made when the model is applied to two level tests.FLAG 发表于 2025-3-25 09:41:18
Prolegomena to the Basic Concepts,The formalism of continuum damage mechanics is utilized in a two state variable physically oriented description of creep behaviour in the single crystal superalloy SRR 99 crept at constant load and temperature in the 750 – 950°C range. The adopted description is excellent at 850 – 950°C while it is less satisfactory at 750°C.Abominate 发表于 2025-3-25 15:09:05

High Temperature Fatigue,high steady state temperatures the fast temperature transients during the start or stop cycles have resulted in sharp temperature gradients at the surface of the components. These surface conditions are very demanding of the fatigue performance of advanced high temperature alloys. As a consequence,etidronate 发表于 2025-3-26 09:21:09
