Abstract This paper is focused on the post-buckling behavior of the fixed laminated
composite beams with effects of axial compression force and the shear deformation. The
analytical solutions are established for the original control equations (that is not
simplified) by applying the Maclaurin series expansion, Chebyshev polynomials, the
harmonic balance method and the Newton’s method. The validity of the present method
is verified via comparing the analytical approximate solutions with the numerical ones
which are obtained by the shooting method. The present third analytical approximate
solutions can give excellent agreement with the numerical solutions for a wide range of
the deformation… More >
