Title: Differental quadrature method for nonlinear dynamical behavior of a viscoelastic Timoshenko beam
Abstract: By the extended differential quadrature(DQ)method,the motion equations governing the dynamical behavior of a visco-elastic beam with finite deformations were discretized,and the nonlinear governing equations could be converted into an explicit matrix form in spatial domain.The dynamic behaviors of the visco-elastic beam were numerically analyzed by introducing new variables in time domain.The classical methods in nonlinear dynamics were applied to reveal dynamical phenomena of the visco-elastic beam.The convergence and comparison of solutions were studied.The results showed that the DQ method presented here is very reliable and effective;at the same time,the influences of geometric and material parameters on dynamic behaviors are investigated.
