Optimum stacking sequences for extension–twist coupled composites subject to thermal stresses
Optimum stacking sequences for extension–twist coupled composites under thermal stresses are determined. An optimization technique is utilized to determine the optimum stacking sequences. An alternative method is developed based on the identification of a parameter controlling
the optimum stacking sequence. Comparison of associated extension–twist coupling values demonstrates their accuracy. It is observed that as the number of plies increases, the optimum stacking sequence follows an asymptotic behavior and that an angle ply system does not represent an optimum
stacking sequence. The results are validated through manufacturing of candidate laminates.
