a In addition to the steadystate secondary creep strain rate

(a) In addition to the steady-state (secondary) creep strain rate, _ss, list three other parameters that we can use to characterize the creep properties of a material. (b) Give their definitions.

Solution

>> In addition to the steady-state (secondary) creep strain rate,three other parameters that we can use to characterize the creep properties of a material are :

1). Instantaneous elastic strain

It means the strain which is present elastically in the body at a particular instant

2). Rupture Lifetime

It indicates the lifetime, when the material is going to fail

3). Creep Deformation

It signifies the deformation at each stage
