Is Creep Elastic Or Plastic?

by

Is Creep Elastic Or Plastic? In general, creep refers to the time-dependent component of plastic deformation. This means that creep is a slow and continuous plastic deformation of materials over extended periods under load. What is plastic creep? Creep is the tendency of a polymeric material to deform permanently under the influence of constant stress,

How Do You Calculate Steady State Creep Rate?

by

How Do You Calculate Steady State Creep Rate? 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
