THE HAMILTON CANONICAL EQUATIONS OF THEORY OF ELASTICITY IN POLAR COORDINATES AND THE VARIABLE CONTROL FINITE ELEMENT METHOD

The Hamilton canonical equations of elasticity in polar coordinate is deduced and the variable control finite element method is proposed. By the-separation of variables,the conventional interpolation method in finite element method is applied in θ direction while the analytical solution is given in r direction, the combined application of the method of finite element and the variable control is rendered.
