What is Monkman Grant relationship?
What is Monkman Grant relationship? Abstract. The interrelationships between the steady creep rate e dot s , time tf to fracture and strain ef to fracture are usually characterized in terms of Monkman-Grant relationships or their modifications. How do you calculate stress creep? Creep rate equation The equation governing the rate of steady state creep is: Q = activation energy; n = stress exponent; A = constant; This can be rearranged into the form: The activation energy Q can be determined experimentally, by plotting the natural log of creep rate against the reciprocal of temperature. What is r in the...
