Abstract: Internal damping in rotating shafts can lead to dynamic instability — the unbounded growth over time of the off-axis displacement of the spinning shaft in whirl. In analyzing this phenomenon, ...

Abstract: The mean-square response of a lightly damped, second-order system to a type of non-stationary random excitation is determined. The forcing function on the system is taken in the form of a ...

Abstract: Various techniques are currently used to simulate a shock environment. The authors investigate the validity of simulating the shock environment due to a pyrotechnic firing by means of a ...

Abstract: The stability of a radially constrained, complete, circular ring subjected to thermal stress and of a similarly restrained portion of a circular ring under circumferential end load is investigated. ...
