Creep Equation Formula

Equation for calculate creep equation is,

$$\frac{\mathrm{dϵ}}{\mathrm{dt}}=\frac{C·{\sigma }^m}{d^b}·e^{-\left(\frac{Q}{k·T}\right)}$$

dt is the time

ε is the creep strain

C is a constant dependent on the material and the particular creep mechanism

m and b are exponents dependent on the creep mechanism

Q is the activation energy of the creep mechanism

σ is the applied stress

d is the grain size of the material

k is Boltzmann's constant [ 1.3806488e-23 J/K ]

T is the absolute temperature
