Stress & Strain
GATE 2018
Easy
In a linearly hardening plastic material, the true stress beyond initial yielding
- increases linearly with the true strain
- Bdecreases linearly with the true strain
- Cfirst increases linearly and then decreases linearly with the true strain
- Dremains constant
Explanation
By definition, a linearly (linear-strain) hardening material has a true stress-true strain curve beyond yield that is a straight line of positive slope — true stress increases linearly with true strain.
