Best power equations model the variable value r0 for dynamically and stress involved in responding to the initial viscosity. While the n variables associated with responding to the viscosity values of creep depends on time.
The model equations are raised r0 parameters for instantly and stress associated with the response to the viscosity began as n variables associated with the response to the viscosity of creep up on time.
The model parameters for stress exponent equation R0 Pronto and associated with the response to the initial viscosity as variables. N associated with the response to the viscosity of creep time dependent.
