The finite element method is widely used in many areas of
engineering and applied science, including structures, fluids, heat
transfer, and electromagnetism. Several commercial programs exist
which have extensive capabilites in these areas, but they usually
require special training and mainframe computers to use. This creates
a series of problems in an engineering organization because of the
inefficiencies of timeshared computer systems and remote processing.
These problems result in poor productivity of the analyst.
This work demonstrates the feasibility of using a desktop
microcomputer to perform finite element structural analysis. A program
is developed which is capable of solving two-dimensional linear static
problems using truss, beam and plane stress elements. The program
includes extensive pre- and post-processing capabilities and graphic
displays. It allows problems with up to 500 degrees-of-freedom to be
solved within a few hours and requires only about one-half hour of
instruction to use. The program theory, a user's manual, and
verification problems are presented.
