Abstract

This paper discusses a three-dimensional solid modelling scheme developed with B-spline as a basis and the techniques for transforming the solid model geometric data into formal solid finite elements. A solid is represented by the scheme as a union of quasi-disjointed cells which are bounded by orthogonal B-spline curves. An algorithm developed converts the cells into solid finite elements. The modelling technique is a powerful tool in the CAD/CAM environment because it is particularly useful for the design and analysis of curved solid mechanical parts.
