Filament Winding Angle Optimization of Composite Shell Under Internal Load

In this manuscript, filament winding angles are selected and enhanced utilizing various methodologiesincluding optimization and numerical validation grounded on failure criteria of orthotropiccharacteristics. Initially, a composite shell is formulated utilizing the Ansys modeling module, followedby subjecting the shell to internal loading. The simulation is conducted employing ANSYS ACP(Pre/Post) and ANSYS Static Structural, with specific parameters specified for executing theoptimization procedure. Upon completion of the optimization process, three potential points areselected based on meeting the optimization criteria. Various orthotropic criteria such as MaximumStrain, Maximum Stress, Hashin, Puck, among others, are integrated into the optimization process.Optimization of ply angles is performed, leading to the attainment of feasible points. Critical regionsare depicted via contours for distinct plies and angles, demonstrating favorable agreement with existingliterature in the obtained results.
