Both … Web13 Oct 2011 · ‘Shock Loading’ refers to a sudden and drastic increase of load similar to a ‘hammering’ effect. The most common occurrence is when a load is dropped onto the ball transfer units from a height or when ball units travel over an uneven surface, causing uneven distribution of load.
Thermal shock is a phenomenon characterized by a rapid change in temperature that results in a transient mechanical load on an object. The load is caused by the differential expansion of different parts of the object due to the temperature change. This differential expansion can be understood in terms of strain, rather than stress. When the strain exceeds the tensile strength of the material, it can cause cracks to form and eventually lead to structural failure.
A mechanical or physical shock is a sudden acceleration caused, for example, by impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation. Shock describes matter subject to extreme rates of force with respect to time. Shock is a vector that has units of an acceleration (rate of change of … See more Shock measurement is of interest in several fields such as • Propagation of heel shock through a runner's body • Measure the magnitude of a shock need to cause damage to an item: fragility.
