One of the major responsibilities of Sandia National Laboratories is to develop shock and vibration specifications for system mechanical, electrical, and pyrotechnic components. The data required to generate these specifications are collected from finite element analyses, from laboratory simulation experiments with hardware, and from environmental tests. The production of the component specifications requires the analysis, comparison, and continual updating of these data. Sandia National Laboratories has also maintained the DOE/DOD Environmental Data Bank for over 25 years to assist in its shock and vibration efforts as well as to maintain data for several other types of environments. A means of facilitating shared access to engineering analysis data and providing an integrated environment to perform shock and vibration data analysis tasks was required. An interactive computer code and database system named GREEDI (a Graphical Resource for an Engineering Environmental Database Implementation) was developed and implemented. This transformed the DOE/DOD Environmental Data Bank from a card index system into an easily accessed computerized engineering database tool that can manage data in digitized form. GREEDI was created by interconnecting the SPEEDI (Sandia Partitioned Engineering Environmental Database Implementation) code, and the GRAFAID code, an interactive X-Y data analysis tool. An overview of the GREEDI software system is presented. 10 refs.
