Question : 2
Total: 21
Figure shows the stress-strain curve for a given material. What are (a) Young’s modulus and (b) approximate yield strength for this material?
Solution:
(a) From graph,
for stress= 150 × 10 6 N m − 2 , the corresponding strain = 0.002
Young's modulus,= 7.5 × 10 10 N m − 2
(b) Approximate yield strength will be equal to the maximum stress it can sustain without crossing the elastic limit
Therefore, the approximate yield strength= 300 × 10 6 N m − 2
= 3 × 10 6 N m − 2 .
for stress
Young's modulus,
(b) Approximate yield strength will be equal to the maximum stress it can sustain without crossing the elastic limit
Therefore, the approximate yield strength
