The strain hardening exponent (also called strain hardening index), noted as ''n'', is a materials constant which is used in calculations for stress–strain behavior in work hardening. In the formula σ = K ε n, σ represents the applied stress on the material, ε is the strain, K is the strength coefficient. The value of the strain hardening exponent lies between 0 and 1. A value of 0 means that a material is a perfectly plastic solid, while a value of 1 represents a 100% elastic solid. Most metals have an n value between 0.10 and 0.50. ==Tabulation== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「strain hardening exponent」の詳細全文を読む スポンサード リンク
