5. A unidirectional fiberglass reinforced epoxy composite is provided with a Vf = 55% volume fraction [43.8 3.72 0 GPa. What stress must be applied to the of fibers. It has a stiffness tensor C = 3.72 0 lamina to generate a strain of = 12.56 0 0 3.55] [0.015] 0.000? (10 points) L0.0101 6. The same lamina as in problem 5 has a stress of o = [200] 150 MPa applied to it at an angle of 0 = 45 50 relative to the fiber axis. What is the resulting strain in the direction of the applied stress? (Note: it may be helpful to draw a picture to visualize the applied stress relative to the fibers). (20 points) 5.
