#### 4.5.1.7 Power Distortional

The material type for this relaxation function is “relaxation-power-distortion”. The following material parameters need to be defined:
 Characteristic relaxation time [t] Power exponent at zero strain [ ] Characteristic relaxation time Power exponent at zero strain Power exponent
The reduced relaxation function for this material type is given by where and The definition of is given in Section 4.5.1.2↑.
