ON THE STABILITY OF ARBITRARY COMPOSITES SHELLS(Ⅰ)——GEOMETRICAL EQUATIONS
-
Abstract: The new non-linear geometrical differential equations for arbitrary composites shells are derived on the basis of 3-dimensional non-linear theory in curveilinear coordinates. The Washizu equation in modified and a more accurate stability equation is expected to be established based upon it.
