Summary on Grant Application Form |
|
This proposal is the first of what is planned to be two linked submissions. EPITOMIZ, the first of two stages, aims to establish an adequately stable and robust numerical algorithm to solve optimisation problems in structural mechanics, where material and geometric nonlinearitiesare strongly coupled and significantly influence the optimal solution.This has been identified as a new area of research. In addition, the novelty of the project is demonstrated by the proposed methodology. The numerical formulation assumes position (nodal co-ordinates) as the state variable, not the displacement as is normally the case. Not only is this approach expected to lead to a solution algorithm with the desired properties, but to provide a natural extension to the determination of shape sensitivities. This potential has already been investigated by Gosling for the 2-D case as a precurser to this grant application. The extension to the 3-D case has been assessed and is entirely feasible within the time frame specified.The primary outcome of this research project will be a proven numerical algorithm, programmed and benchmarked (via NAFEMS). A subsequent grant application is planned to request funding to incoprorate adaptive mesh refinement and multi-point approximation methods into the base algorithm to enhance EPITOMIZ.
