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 amplitudes. What’s more, the effect of shear deformation on the 
post-bucking configuration of the sandwich beam is also proposed. It can be found that the 
shear angle has a great influence on the post-buckling load of composite beams. Therefore, 
the model simplifying the shear formation term as small quantity is not accurate for the case 
of sandwich beam with soft core.},
