Abstract:

The trend in structural analysis in the past two decades has been the development of the finite element methodology. The state-of-the-art of the finite element method is such that most linear structural problems can be solved, provided time and cost are not of concern. For many engineering problems of interest to the Navy, a finite element model may not be as appropriate as a structural member model. The latter may be adequate and, indeed, even more accurate. Hence, there is a pressing need for efficient, accurate structural member solutions. The goal of this project has been to develop structural member dynamic response technology so that it is as reliable as static response methodology, even for complex geometric, material, and loading situations. The technology being developed is computational. Reanalysis formulations, which were developed primarily for discrete systems, are extended to structural members. Studies of design sensitivity, synthesis for prescribed dynamic characteristics, and optimizations under dynamic constraints were performed.
