| Abstract: | The mathematical model for nonlinear analysis of spherical shells is first butt in spherical coordinite,and tangential stiffness matrix of nonlinear finite element is produced.The computer practical programs about nonlinear spherical shells are written.Some examples show that the model is simple,direct and practical,by which the geomplicated questions of geometrical boundary and weighted conditions are easily handled and it may save much c.p.u time in engineering analysis. |
