... of loading: in-phase and out-of-phase cycling. The article illustrates the ways in which damage can interact at high and low temperatures and the development of microstructurally based models in parametric form. It presents a case study of the prediction of residual life in a turbine casing of a ship through...

.... This is called the Otto cycle. In the case of a steam turbine system, the combustion gas is used to boil water inside a heat exchanger; the compression is achieved by pumping the inlet water. The compressed steam is then allowed to expand through a turbine, and it is condensed by a condenser at the turbine...

..., and especially those failure modes that occur in wind-turbine components. Macropitting and scuffing could cause gear teeth to deteriorate and generate dynamic forces, which, in turn, could cause the teeth to fail by bending fatigue. In these cases, the bending failure is secondary and not directly related...
