Abstract
A medial surface generation technique for generating a shell model for finite element analysis of a thin structure has been developed. This method has the advantage of reducing analytic work load. It consists of four steps; first, a pair of thin faces is found; second, a generatrix medial surface of the pair is generated; third, an intersection line between the generatrix medial surface and boundary face of the solid is calculated; fourth, an intersection line is trimmed off the generatrix medial surface. The effectiveness of the technique was confirmed by applying it to the medial surface generation of magnetic disk head parts.
