Chapter 8, Problem 8.1P

Interpretation Introduction

Interpretation:

The "strain hardening" needs to be explained from the stress-strain diagram.

Concept introduction:

The stress-strain diagram is used to determine the physical deformation of a material. Through a stress-strain curve, one gets various regions such as elastic regions and plastic regions.

Answer to Problem 8.1P

In The stress-strain diagram, strain hardening is the applied stress on the material which causes the deformation of the material.

Explanation of Solution

Strain hardening is also called as work hardening or cold working. In strain hardening strengthening of material takes place so that material goes under plastic deformation.

Strengthsdue to dislocation movements within the crystal structure of the material.

As per the stress-strain diagram the strain hardening in which the stress is applied on the metallic material, Due to this stress, it causes an increase in the original yield strength which causes deformation.

Strain hardening is widely used in the manufacturing sector for the wire drawing technique.

Conclusion

Thus, the strain hardening causes deformation of the material which increases the yield strength and deforms the material.
