Question
The loading and unloading response of a metal is shown in the figure. The elastic and plastic strains corresponding to 200 MPa stress, respectively, are
Options :
0.01 and 0.01
0.02 and 0.01
0.01 and 0.02
0.02 and 0.02
Answer :
0.01 and 0.02
Solution :
Plastic/Permanent strain = OB = 0.01
Elastic strain = BC = 0.03 - 0.01 = 0.02
