DQEM analysis of in-plane vibration of curved beam structures

The development of differential quadrature element method (DQEM) in-plane vibration analysis model of arbitrarily curved beam structures was carried out. The DQEM uses the extended differential quadrature to discretize the differential eigenvalue equation defined on each element, the transition conditions defined on the inter-element boundary of two adjacent elements and the boundary conditions of the beam. Numerical results obtained by the developed numerical algorithm show that the convergence of the developed DQEM analysis model is efficient.
