关键字：Differential quadrature element method Multiple boundary conditions Hybrid nonlocal Euler-Bernoulli beam Free vibration

摘要：A novel differential quadrature element method is presented for free vibration analysis of hybrid nonlocal Euler-Bernoulli beams with any combination of boundary conditions. Explicit formulas of computing the weighting coefficients of various derivatives are derived. Sixth-order differential equations are successfully solved by using the proposed method. Accurate frequencies are obtained and presented. The proposed method can be also used for accurate solutions of various sixth-order differential equations and beam structures with minimum computational effort. (C) 2017 Elsevier Ltd.
