Composite pressure vessel analysis with Semi-Geodesic winding
Nowadays, pressure vessels are produced using various methods, one of which is filament winding. This package teaches the simulation of composite pressure vessels produced using the filament winding method. Filament winding itself has different methods, and one of the most widely used winding methods for producing composite vessels is the semi-geodesic filament winding method. In this package, first, the semi-geodesic method is described. Then, the simulation of a semi-geodesic vessel is performed using a Python script. Additionally, a UMAT subroutine is used to simulate the failure of composite materials used in the vessel.
