A bimetallic bar is made by two homogeneous rectangular bars bonding together, each having a width b and length L. The moduli of elasticity of the bars are E1 and E2, respectively. An axial force P is applied to the ends of the bimetallic bar at (y = yP, z = 0) such that the bar undergoes axial deformation. Let L = 1.5 m, b = 50 mm, t1 = 25 mm, t2 = 15 mm, E1 = 70 GPa, E2 = 210 GPa, and P = 48 kN.
