What are the three types of mechanical behavior (stress/strain curves) during tensile test? What are the types of materials that have these three types of mechanical behavior respectively?

Check Explanation.

Explanation:

The three types of mechanical behavior (stress/strain curves) during tensile test include:

- Plasticity - ability to be easily moulded or shaped. Ability to be permanently deformed in response to applied force.

- Ductility - ability of a material to be hammered thin or stretched into wire without breaking

- Elasticity - ability to retain its original shape after a force causing extension or compression is removed.

The types of materials that have these three types of mechanical behavior respectively are:

Plasticity - Some ceramics, clay

Ductility - Metals.

Elasticity - Polymers (plastics)
