Transient friction loading is the mechanical stress induced on an object due to transient or vibrational frictional forces.
[1] A classic example of transient friction loading is the wooden block sliding over an unlevel, non-planar surface.
The induced stress is concisely described as transient friction loading.
Another is the internal stresses on a hydraulic ram operating in a vibrational environment.
[3] Due to the oscillatory nature of the acceleration experienced by the ram, in n-dimensions, the resulting frictional response is described as transient friction loading.
