Using the values of stress components from Q1 above, and taking v=0.3 and E=69 GPa determine the following: A) The Principal Strains. B) The largest Shear Strain in X-Y plane. C) The Strain Energy Density (Strain energy per unit volume). If the values of txy= tyx=0 in Q1 above, and the element is subjected only to stresses, ax=16000 MPa, oy=6000 MPa A) What are the differences of the results of a, b, and c above for Q1? B) Discuss the differences. An element in plane stress is subjected to stresses, o, = 16000 MPa, o, = 6000 MPa, and Ty = Tyx = 4000 MPa (as shown in figure below). Using the Mohr's circle, determine the following: A) The stress components with respect to ab axes which are inclined at e = 45 to the xy (10 Marks) (7 Marks) c) Locate the axes of Maximum shear stress and evaluate the corresponding stress axes. B) Locate the principal axes and evaluate principal stresses. components. (7 Marks) yt 6000 MPa a 4000 MPa 45 X 16000 MPa Fig. Ql: An element in plane stress
