Size dependent vibration of laminated micro beams under moving load
Ş.D. Akbaş
Abstract
The goal of this paper is to investigate dynamic responses of simply-supported laminated micro beams under
moving load. In the considered micro-scale problem, the modified coupled stress theory which includes the length scale
parameter is used. The governing equations of problem are derived by using the Lagrange procedure. In the solution of the
problem the Ritz method is used and algebraic polynomials are used with the trivial functions for the Ritz method. In the
solution of the moving load problem, the Newmark average acceleration method is used in the time history. In the numerical
examples, the effects of stacking sequence of laminas, fibre orientation angles and the length scale parameter on the dynamic
responses of laminated micro beams are examined and discussed.
