Local strain meaning
In materials science, strain rate is the change in strain (deformation) of a material with respect to time. The strain rate at some point within the material measures the rate at which the distances of adjacent parcels of the material change with time in the neighborhood of that point. It comprises both the rate at which the material is expanding or shrinking (expansion rate), and also the rate a… Witryna13 kwi 2024 · The log-normal form observed for the local strain distributions supports this interpretation as this distribution can result as a product of many random variables. Indeed log-normal strain ...
