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.
