Hi All

If I have three shells that are joint to eachother , and i have to make a composite lay-up out of them , if I have the stiffness matrix of each shell , 6x6 matrices , to build up this composite lay-up , how to I assign the matrices to build the global stiffness matrix ? does each of the stiffness matrices of the shells counted as a [Q] , compliance matrix ?
