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?

Answer :

Answer:

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)

Answer:

The three types of mechanical behaviour (stress/strain curve) and their materials includes:

1. Perfectly Elastic: Glass, Ceramics, Cast Iron etc

2. Rigid Plastic: Cups, High Density Polyethelene tubs, Similar food containers etc

3. Elastic, Perfectly Plastic: solid shaft, Lead etc

Explanation:

1. In Perfectly Elastic Materials, there is negligible yielding. Here the stiffness of the material is indicated

2. In Rigid plastic: the materials continue to deform at the same rate/level once stress level has reached the yeild point.

3. In Elastic Perfectly Plastic: this is a combination of both perfectly elastic and rigid plastic, materials heated at a very high temperature behave in a way that it will undergo recovery when loading.
