In this paper, a finite element analysis of shells of revolution using cubic B spline is presented. In this method, both the three components of the displacement of a point on the middle surface of a shell and the meridianal geometric shape are approached by using spline functions whose cardinal splines are cubic B spline. Compared with the ordinary finite element method, the proposed method pos sesses the following advantages: such as lower order of polynomials and less degree of freedom, but higher order of...

Deals wiih the two-dimensional frictionlcss clastic contact problems by way of boundary element method. Analyzing both the conditions of equilibrium and coordination to be satisfied in the different cases of contact, the boundary conditions are expressed in cither case that a boundary is possibly or has already been in contact with, the other. A boundary integral equation based on elastic mechanics is then applied and it becomes algebraic for numerical solution by discretizing the boundary into several linear sets. The iteration computation is simplified in such a way that the criteria of the states of inset and normal pull between two boundaries are merely limited to the case of possible contact boundary. The final solution obtained involve the contact zone and the tractions and displacements on the whole boundary especially the distribution of contact pressure. With two instances included the result is proved Jess number of nodes, simpler data preparation. more rapid computation speed and higher precision in comparison with finite element method.
