Problem: The 45 strain rosette is mounted on a steal beam subjected to plane strain loading. The following reading are obtained for each gauge: Ea 650 x 106, Eb-300 x 106 and e 480 x 106. The beam is = = made from steel alloy having E-200 GPa and v = 0.33 Determine: (a) the plane strain components Ex, Ey and Yxy (b) the principal strains and the maximum in-plane shear strain and associated average normal strain. (c) the principal stresses 1, 02 and 03. (d) the maximum absolute shear stress. 45 45
