Wave propagation in fibre-reinforced cylinders
R. R. Mukhomodyarov, Ya. A. Parfenova Saratov State University, Chair of Mathematical Theory of Elasticity and Biomechanics
Abstract:
Non-stationary wave propagation in cylindrical composite shell is considered. The shell consists of isotropic matrix reinforced by two families of symmetrically wound spiral fibres. These families have the same mechanical properties and the cylinder is considered to be incompressible. Solutions of coupled equations of motion are
represented in the form of Frobenius power series. Approximate dispersion relation derived is analyzed numerically for different shell thicknesses and fibre winding angles.
Key words:
non-stationary waves, fibre-reinforced composites, Frobenius series, dispersion relation.
