Free Vibrations Analysis of Laminated Composite Rotating Beam using C' Shear Flexible Element
AbstractThe free flexural vibrations of rotating beam made of anisotropic laminated composite beam are investigated using a new three noded finite element. The governing equations for the free vibration of rotating beam are derived using Lagrange's equation of motion. The element employed is based on shear flexible theory. It also includes inplane and rotary inertia terms. The formulation takes care of continuity conditions for stresses and displacements at the interfaces between the layers of a laminated beam. Numerical results for uniform rotating cantilever beam are presented by considering various parameters like slenderness ratio, modular ratio and rotational speed, etc.
