Q4) Fig. Q4 shows the cross-section of a hollow box beam which is symmetric with respect to the x- and y-axes. Assume an ideal elastic/perfectly plastic material for the beam. The dimensions, material properties and load magnitude for each group are shown in Table Q4. c) Calculate the residual stress distribution for the unloaded beam and the corresponding radius of curvature. Assume elastic springback during unloading. yî yî t B(mm) H(mm) (mm) E(GPa) t Oy=Yield strength (MPa) 290 H h Х 45 125 4.2 71 Plastic zones b! t Fig. Q4
