Abstract
Governing equations for the dynamic and flexural behavior of a rotating sandwich tapered beam with two nonsymmetrical facings are formulated by using the variational principle. Because of the asymmetric geometry and the centrifugal effects, the neutral axis does not necessarily coincide with the centroidal axis. The analysis takes this behavior into consideration and, therefore, differs from existing formulations substantially. Both the core and facings are consistently modeled as either Timoshenko beams or Euler-Bernoulli beams. The flexural behavior of tapered sandwich rotating beams with uniformly or linearly distributed loads is investigated by solving the governing equation using the finite-difference technique.
