Work materials experience a broad range of strains, strain
rates, and temperatures in many manufacturing processes such
as machining, forming, etc. Strain rate has an important effect
on the yield and flow stress of work materials, especially
metals, since at higher strain rates there is less time for
thermally-activated events consequently, it is equivalent to a
lowering of the temperature of the materials.
