The medial axis of a solid is the locus of inscribed circles/spheres with maximum diameters such that the
circles/spheres touch the maximum number of edges/surfaces of the solid, without intersecting with any of
them. Although a medial axis/surface may appear to be similar to the corresponding mid-surface of the solid,
it stores information regarding the thickness of the section. Based on this feature of medial axes, an innovative
and computationally inexpensive solidi!cation interpolation method is proposed in this paper. The method
o5ers a compromise solution between traditional numerical methods and the geometry driven section modulus
methods. Even though the proposed method may not be as accurate as traditional numerical methods, it gives
a rapid “feel” of the design to its creator during the interrogation stage. The solidi!cation results are compared
with a !nite element simulation as well as the simple section modulus method. The potential bene!ts of this
technique can be realised during an optimisation cycle where repetitive calculations are needed even for small
design changes.
