Consider graphite/epoxy cross-ply laminated beam supported and loaded as shown in Figure 7. The beam is 550 mm long and 25 mm wide. The thickness of the beam is 3 mm. The stacking sequence is [(0/90)3] Consider the following lamina properties: E. = 250 GN/m Ex = 10 GN/m 5. (+) = 1950 MN/m S. (-) = 1550 MN/m ST (+) = 45 MN/m ST (-) = 240 MN/m G12 = 9.5 GN/m V = 0.3 Shear Strength = 950 MN/m² (0) Calculate the flexural modulus and elastic modulus of the beam. (10%) (ii) Determine the magnitude of the maximum running load (w) and the resulting deflection that the beam can withstand. Use maximum stress criterion. Further also indicate which ply would fails first. (5%) (ii) Sketch the stress distribution through the thickness of the beam using FEA to check your results. (5%) (iv) You are to reduce the tip deflection by 10% determine a new layup for the beam. Comment on your final design. (10%) w EL 250mm 300mm z Figure 7
