The flow stress of the material changes with deformation, so called strain hardening or workhardening behaior and may be influenced by the rate of deformation.
材料的流量应力变化伴随着材料变形,这就是应变硬化或加工硬化特性而且会收到变形率的影响。

Work hardening
（重定向自Strain hardening）
Work hardening, also known as strain hardening or cold working, is the strengthening of a metal by plastic deformation. This strengthening occurs because of dislocation movements and dislocation generation within the crystal structure of the material. Many non-brittle metals with a reasonably high melting point as well as several polymers can be strengthened in this fashion. Alloys not amenable to heat treatment, including low-carbon steel, are often work-hardened. Some materials cannot be work-hardened at low temperatures, such as indium, however others can only be strengthened via work hardening, such as pure copper and aluminum.
