How to Calculate and Solve for Relationship between Creep Strain Rate and Temperature | Fracture
Last Updated on December 16, 2022
The image of relationship between creep strain rate and temperature is represented below.
To compute for relationship between creep strain rate and temperature, six essential parameters are needed and these parameters are Activation Energy for Creep (Qc), Stress (σ), Gas Constant (R), Temperature (Kelvin) (T), Constant (k2) and Constant (n).
The formula for calculating relationship between creep strain rate and temperature:
εs = k2σnexp(-Qc/RT)
Where:
εs = Creep Strain Rate
Qc = Activation Energy for Creep
R = Gas Constant
T = Temperature (Kelvin)
σ = Stress
k2, n = Constant
Given an example;
Find the creep strain rate when the activation energy for creep is 2, the gas constant is 6, the temperature is 7, the stress is 4, the constant is 8 and the constant is 5.
This implies that;
Qc = Activation Energy for Creep = 2
R = Gas Constant = 6
T = Temperature (Kelvin) = 7
σ = Stress = 4
k2 = Constant = 8
n = Constant = 5
εs = k2σnexp(-Qc/RT)
εs = (8)(4)5exp(-(2)/(6)(7))
εs = (8)(1024)exp((-2)/(42))
εs = (8)(1024)exp(-0.047)
εs = (8)(1024)(0.95)
εs = 7811.04
Therefore, the relationship between creep strain rate and temperature is 7811.04.
