Question 6 A symmetric laminate consisting of 0.25 mm thick unidirectional AS/3501 Carbon/Epoxy laminae has the stacking sequence [+45°-45°)s (a) In the usual notation and using classical lamination theory, determine the A, B and D matrices of the laminate. [10 marks] (b) The laminate is subjected to a single uniaxial force per unit length Nx = 50 MN/mm in the X-direction. Determine the resulting stresses associated with the X and Y axes in each lamina.
