An engineer needs a material for springs with minimal permanent deformation under load. Which property - alloy combination best satisfies this requirement?

The creep mechanism observed at very low stresses with stress exponent $n=1$ is given by

In Dynamic hardness testing, the hardness is measured by

The correct statement for a cold-worked material is

Fatigue data are commonly presented using

The two statistical methods used for making a statistical estimate of the fatigue limit are

In Andrade's analysis of creep, the two components that together form the creep curve are

Consider the following Assertion (A): The shape and magnitude of the stress-strain curve of a metal depend on its composition, heat treatment, prior plastic deformation, strain rate, temperature and state of stress during testing. Reason (R): Tensile strength and yield strength are strength parameters, whereas percent elongation and reduction of area are measures of ductility.

The fundamental assumption behind Barba's law in tensile testing is that

The stress at which the stress-strain curve deviates from linearity is:

The basis on which the Von Mises criterion is preferred compared to maximum shear stress criterion theoretically is:

Match the following:
