The research includes a new approach to develop more accurate and               efficient techniques for solution of three dimensional problems with            discontinuities and local nonlinearities.  The finite element method            owes its significance to its potentiality for the treatment of rather           arbitrary geometry, and different material properties.  One may build           a special finite element that contains the discontinuity in the                 element formulation, and couple the special element to the mesh that            models the rest of the system.  The special element formulation,                unlike others, will incorporate already existing classical solutions            into the element formulations.  The displacement function, for                  structural problems for example, used in approximations will exactly            satisfy the analytical results wherever available.  This will be                achieved by invoking the classical solutions as constraints in the              derivation of element stiffness coefficients.  This research will               bring about a new technique to handle discontinuities, local                    geometric-material nonlinearities at local level without requiring              mesh refinements.  For numerical comparison purposes a computer                 program will be developed.
