Strain rate is defined as the change in strain (deformation) of a material with respect to time .
Strain rate is the time derivative of strain of a material. Strain rate has dimension of inverse time and SI units of inverse second, s −1 (or its multiples). The strain-rate tensor · Sliding rate or shear strain rate |

В механике и материаловедении скорость деформации — это производная по времени деформации материала. Скорость деформации имеет размерность обратного времени и единицу СИ — обратную секунду, с⁻¹. Википедия (Английский язык)
Strain rate refers to the sensitivity of plastic deformation to time scales, characterized by the rate of strain under a specific stress and strain condition. |
