SEMI-ANALYTICAL APPROACH TO THE ANALYSIS OF THE NONSYMMETRIC FILAMENT WOUND COMPOSITE MODEL

This work deals with an analysis of deformation of thick-walled filament wound composite model. The static deformation analysis and the dynamic analysis are described in detail. The oscillations of the model are solved using the action integral, Euler-Lagrange equations for the action integral and the singular value decomposition. The problems are solved using the principle of the total potential energy minimum, the concept of the locally orthotropic material, the semi-analytical method, anisotropic elasticity in curvilinear coordinates, and the Fourier series expansion. The nonsymmetric model with nontrivial cross section is used to describe the methods.
