Frequency and Strain Rate in Fatigue Testing: Does Test Speed Matter?
Introduction A question that comes up regularly in fatigue testing and vibration qualification programs is whether the frequency of cyclic loading — or the associated strain rate — influences the fatigue life of a component. The honest answer is: it depends very much on the… Read more
Estimating Dynamic Strain in Rubber Vibration Isolators from Acceleration Measurements
Estimating structural strain in a rubber vibration isolator from acceleration measurements is a challenging problem because elastomers behave very differently from metals. Their stiffness is strongly frequency dependent, highly temperature sensitive, and inherently viscoelastic. Nevertheless, useful engineering estimates can often be obtained from vibration measurements… Read more

SCUD-B Typical Avionics Component The avionics shelves were made from hardwood. The wooden fibers may provide better damping then, say, an aluminum shelf. A possible disadvantage of wood is that the shelf would be unable to serve as an electrical or thermal ground plane. The… Read more
