摘要: A refined 2-node, 4 DOF/node beam element is derived based on higher order shear deformation theory for axial–flexural-shear coupled in asymmetrically stacked laminated composite beams. The has an exact shape function matrix, which by satisfying the static part of governing equations motion, where a general ply-stacking considered. This makes super-convergent analysis. numerical results are validated considering uniformly distributed load with various boundary conditions. Subsequently, efficiency free vibration analysis studied. Numerical examples showing nature interlaminar stresses configurations and conditions demonstrated. Also, parametric studies performed to study effect coupling stiffness natural frequencies. Based these studies,number observations drawn.
