Question

Two tempered-steel bars, each 316316 in. thick, are bonded to a 1212 -in. mild-steel bar. This composite bar is subjected as shown to a centric axial load of magnitude P. Both steels are elastoplastic with E = 29 × 10⁶ psi and with yield strengths equal to 100 ksi and 50 ksi, respectively, for the tempered and mild steel. Determine the residual stresses in the tempered-steel bars if the load P is gradually increased from zero to 103 kips and then decreased back to zero. The residual stress in the tempered steel bars is

Two tempered-steel bars, each in. thick, are bonded to a -in. mild-steel bar. This composite bar is
subjected as shown to a centric axial load of magnitude P. Both steels are elastoplastic with E= 29 × 106 psi
and with yield strengths equal to 100 ksi and 50 ksi, respectively, for the tempered and mild steel. Determine
the residual stresses in the tempered-steel bars if the load Pis gradually increased from zero to 103 kips and
then decreased back to zero.
