An elastoplastic bar is clamped at the left end, and variable loads are applied at the right end, as shown in the table. Plot the stress-strain curve by changing the applied forces by 5 kN increments.

Assume the following material properties with isotropic hardening: E = 70 GPa, H = 10 GPa, σ_Y= 250 MPa. The length of the bar is L = 1 m, and the cross-sectional area is A = 1.0 X 10^-4 m².

Load Step	1	2	3	4
Force (kN)	30	20	35	20
