Abstract
In this study, an experimentally validated numerical analysis was performed toward optimization of stacking sequence
in multidirectional laminated composites subjected to low-velocity impact. For this purpose, an optimization program
was developed by integrating finite element method and Multi Objective Genetic Algorithm using modeFRONTIER.
In this regard, three objective functions were defined; one, based on Hashin failure theory and two others based on
interlaminar shear and tensile stresses. These objective functions were aimed to be optimized through tailoring
ply angles with special focus on minimizing impact-induced damage. The obtained results indicated that the
proposed optimization method is an effective tool for optimizing stacking sequence of laminated fiber-reinforced
composite materials.
