Question 4 (20 marks) An element of an orthotropic lamina is subjected to an off-axis shear stress Txy at an angle 0 as shown below. (a) For an angle 0 = 45°, determine the value of the applied shear stress Txy that would generate the following stresses along the 1,2 axes: 01 = 1000 MPa, 02 =-1000 MPa, and T12 = 0. (b) Assuming that the lamina described in part (a) is made from T300/934 carbon/epoxy and that the stresses are also given in part (a), determine the strains along the 1,2 axes. (Note: Find the engineering constants from the lecture note.) Txy (MPa) ху Try (MPa) 2 1 Ꮎ X
