Numerical approach for laminated composite beam using differential quadrature method

The generalised beam theory for laminated composite beams is used to study the vibrational response of laminated composite beams. The material and inertial coefficients values is calculated for CFRP, Gr-Ep, Gl-Ep and Br-Ep. The differential quadrature method is used to solve the governing equations of laminated composite beam. The weighting coefficients are generated from the Lagrange polynomial function. The governing equation of laminated composite beam is solved for clamped-free and simply supported conditions.
