| Abstract: | In this paper a Semi-Analytical Element Method has been suggested, which is unique in that concepts of stiffness matrix are dispensed with.
In this method the given elastic body is subdivided into its imaginary jndividual components or "elements".For every element some trial functions are adopted. At given points the trial functions have to satisfy the boundary conditions and continuous conditions.
The suggested method may be widely used for solving nonlinear problems of solid mechanics and other types of problems. |
