1 The 45° strain rosette is mounted on a surface of the bracket as shown in Figure Ql. The bracket is made from steel with Eseel = 120 GPa and poison ratio, v = 0.28. The following readings are obtained for each gauge under loadings: Ea=[X+Y] (10*) Es = -200(10-6) E= -180(106) Important note : X=100 Y=60 (a) Prove that &=Ea and &= E,. (b) Determine the shear strain, y and the normal strain, &, and E,. (c) Estimate the in-plane principal strains and the angle associated with the principal strains, and
(b) A differential element on the bracket as shown in Figure 1 is subjected to plane strain that has the following components: ex = 150µ, ey = 200µ, yxy = -700µ. By using the strain transformation equations, determine: - (i) The equivalent in-plane strains on an element oriented at an angle 0 = 60° counterclockwise from the original position. (ii) Sketch the deformed element within the x' – y' plane due to these strains. (iii) The stresses on the oriented planes in (I) where the value of elasticity, E = 200 GPa and Poisson's ratio, v = 0.32. (iv) Give your comments on those stresses in (iii) in terms of elastic limit/failure if the material's yield strength in tension/compression is 250 MPa and in shear is 90 MPa.
