Which types of stress strain relationship best describes the behaviour of brittle materials as ceramics and thermosetting plastics?
Directions: Each of the next items consists of two statements, one labeled as the ‘Statements (I)’ and the other as ‘Statement (II)’. You are to examine these two statements carefully and select the answers to these items using the codes given below:
Statements (I): Ductile materials generally absorb more impact energy than the brittle materials. Statements (II): Ductile material generally have higher ultimate strength than brittle materials.
Malleability is the property by which material can
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:
If stress values is measured during the tensile test, then which of the following have higher actual value than initial value?
Which mechanical property determines the stiffness of a material?
