... Critical turbine engine and aircraft components fabricated from continuous fiber-reinforced metal matrix composite (MMC) will experience cyclic loads during service, and many of these components typically contain crack initiators. Hence, extensive characterization of the fatigue crack growth...

... is a function of the applied stress or strain, temperature, etc. Many alloys recrystallize below 77°F (25°C) and therefore can change with time at room temperature. A program of characterization involving tension tests at various temperatures and strain rates, creep tests, cyclic loading tests, and tension...

... The objective of this paper is to illustrate the application of a recently developed inelastic failure analysis method to frames under proportional cyclic loading. The method takes into account the effect of bending moment and axial force interaction in the formation of plastic hinges during...

... was used for large-scale tests in the high level vibration test program, which applied intense cyclic loadings to reactor piping system components and revealed that fatigue crack growth could be a serious problem in these components. The tests conducted included monotonic and cyclic tension tests...
