The nine-node Lagrangian isoparametric finite element is used to derive the element stiffness matrix and geometric stiffness matrix. The originally coded MATLAB programme is used to analyse the effects of side to thickness ratio a/b, aspect ratio a/b, ply-orientation angle theta, modulus ratio E-1/E-2, thermal expansion coefficient ratio. alpha(2)/alpha(1,) temperature distribution and different boundary conditions, on thermoelastic stability of laminated composite plates.
