Abstract : The final report presents a procedure which combines infinite field solutions with the finite element method to represent the domain of interest in semi-infinite problems. This approach reduces computer time required and increases the accuracy of solution for such problems. The method involves approximating the displacements of the system by global displacement functions which may extent to infinity, and correcting these functions by finite element displacements within regions of the structure where discontinuities in materials and geometry occur. An operating computer program has been developed for the two-dimensional analysis of solids. (Author)
