This paper on "An Information for Shape and Computational Analysis Developed Using the STEP Methodology" was presented at the 5th International Conference on Reliability of Finite Element Methods for Engineering Applications - 10-12 May 1995, Amsterdam, The Netherlands.

Summary

The paper will describe an information model derived to integrate more closely than is common today, shape representation and (engineering) analysis. The model is being used to provide both a "data exchange" interface and a "shared data" environment for use by CAD, and in the first instance, CFO although the model incorporates information to support stress analysis and the geometry for layer manufacture. The model has been derived using the methodology evolving to support the development of STEP, the STandard for the Exchange of Product models. The work reported is part of the CARP3 project which aims to review the influence of layered manufacturing (so called rapid prototyping) on both the design cycle and preparation for manufacture for automotive power train components in order to reduce lead times. A core requirement is an integration of the activities which are supported by software within these processes.
