Stress-strain curves are an important graphical measure of material’s mechanical properties. It is seen that strain energy increases quadratically with the stress or strain; i.e. that as the strain increases the energy stored by a given increment of additional strain grows as the square of the strain.
In the Stress Strain Curve as shown, point U is known as:
Hook’s law of proportionality in the diagram can be explained between point:
Which types of stress strain relationship best describes the behaviour of brittle materials as ceramics and thermosetting plastics?
If stress values is measured during the tensile test, then which of the following have higher actual value than initial value?
Medium temperature tempering increases i) endurance limit ii) elastic limit iii) hardness
The point U in Stress Strain Curve shown represents:
