Transient friction loading is the

mechanical stress In continuum mechanics, stress is a physical quantity. It is a quantity that describes the magnitude of forces that cause deformation. Stress is defined as ''force per unit area''. When an object is pulled apart by a force it will cause elonga ...

vibration Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The word comes from Latin ''vibrationem'' ("shaking, brandishing"). The oscillations may be periodic, such as the motion of a pendulum—or random, su ...

friction Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: *Dry friction is a force that opposes the relative lateral motion of ...

A classic example of transient friction loading is the wooden block sliding over an unlevel, non-planar surface. Due to the transient response of the contact force, the resultant frictional force is noisy. The induced stress is concisely described as transient friction loading. Another is the internal stresses on a

hydraulic ram A hydraulic ram, or hydram, is a cyclic water pump powered by hydropower. It takes in water at one "hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The device uses the water hammer ef ...

operating in a vibrational environment.Brown, Samuel, "An Analysis of Hydraulic Ram Dynamics," 1981. 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.
