QUESTION: 1

### Flow stress corresponds to

Solution:

The stress required to cause the metal to flow plastically to any given strain.

QUESTION: 2

Solution:
QUESTION: 3

### The loss of strength in compression due to overloading is known as

Solution:

(Bauschinger effect and hysteresis loop) Due to stress loading unloading, the yield stress in tension gets increased and yield stress in compression gets decreased. This decreasing of yield stress in compression is the Bauschinger effect.

QUESTION: 4

Rupture stress is

Solution:
QUESTION: 5

The property of a material by virtue of which it can be beaten or rolled into plates is called

Solution:

it is a property of material allows it to expand in all directions without rupture. A malleable material has to be highly plastic, though it may not posses high stress. This property is of great use in processes such as forging, hot rolling, etc.

QUESTION: 6

Hardness is the resistance to

Solution:
QUESTION: 7

Brittle materials generally fail by shearing along the planes inclined at ____ to the longitudinal axis.

Solution:
QUESTION: 8

The change in the unit volume of a material under tension with increase in its Poisson’s ratio will

Solution:

∴

QUESTION: 9

True stress-strain curve for material is plotted between

Solution:
QUESTION: 10

Consider the following statements about truestress-strain method/curve:
1. It is more sensitive to changes in both metallurgical and mechanical conditions.
2. It gives a more accurate picture of the ductility.
3. It can be correlated with stress-strain values in other tests like torsion, impact, combined stress tests etc.
4. It can be used for compression tests as well.

Which of the above statements are correct?

Solution:
