Find the local stresses at the top of the 60° ply in a [0/60/–60] graphite/epoxy laminate subjected to a bending moment of Mx = 50 N-m/m. Use the properties of a unidirectional graphite/epoxy lamina from Table 2.1 and assume the lamina thickness to be 0.125 mm. What is the percentage of the bending moment load taken by each of the three plies?Find the local stresses at the top of the 60° ply in a [0/60/–60] graphite/epoxy laminate subjected to a bending moment of Mx = 50 N-m/m.
