英文摘要: Based on the object-oriented database and its concept, in conduct with multi-purposes of engineering designs, the poposed project will focus on an FEA supporting plateform for CAD/CAE software. Mining the supporting points of computation software system to engineering designs, an open, multi-purposed prototype software will be studied and developed which is supposed to be a general, flexible and highly-efficent software tool prototype. The core of this research covers procedure modelling of engineering design and database management of complex engineering data, as well as computational mechanics algorithms in corresponding designs. The project will develop a high-efficient in-core and out-of-core data management system, study practical integration approaches of software, build interface between design data and computational data, as well as interface between data and features. The research will test, modify and integrate existing numerical approaches, and will destinate a efficient and reliable frame of design and computational software. We will deliever an advanced stratege for medium to large engineering designs. In cooperation with corresponding software houses for building or bridge, the prototype plateform will be validated, varified and modified. The final result is an open source of computational softwar
