Composite Materials Design Database and Data Retrieval System Requirements.

摘要

The emergence and use of composite materials in engineering applications have increased considerably. A need, therefore, exists to make information available about composite materials, their derivation, their properties, and their use, to researchers and material engineers. To do so requires a greater understanding of the problems and solutions that emerge when integrating composite materials data with computer database technology. Gaining such an understanding will facilitate the eventual development and operation of utilitarian composite materials databases (CMDB) designed to support a collection of analysis and design software. The objective of this report is to establish the requirements for creating a composite materials design database and data retrieval system for use in ballistic applications. The target database is fundamentally an engineering properties database that is designed to support the needs of the analysis, design, and data retrieval software. Of particular concern are the representation of material property data in terms of a data model, interfaces to application software, data retrieval applications, and the role of expert systems in composite material design. Each of these needs is discussed in this report. The eventual objective is to develop a prototype database environment to support these needs. To do so requires a combination of the fields of materials engineering and computer science.
