Patent ID: 8335669

Claim:
A method for analyzing mechanical behavior of a golf ball comprising: preparing a model representing a golf ball by a collection of hexahedral elements; setting nodes at vertexes and sides of the hexahedral elements, the hexahedral elements adjacent to each other sharing the nodes; and computing mechanical behavior involving deformation of the golf ball by using a finite element method using the elements and nodes of the model, the nodes being used as output points of computation, wherein the aspect ratio of the shape of each of the elements is not lower than 1.0 and not higher than 6.5, the model is divided into a plurality of zones separated from each other by a spherical face whose center is the center or the center of gravity of the golf ball, the plurality of zones include a core zone having the center or the center of gravity of the golf ball therein and a outer layer zone positioned around the outside of the core zone, the hexahedral elements in the outer layer zone are defined without dividing into finer sized sections in the radius direction than the hexahedral element in the core zone, and in the elements in the core zone, a volume ratio, which is a ratio of the volume of an element having the maximum volume to the volume of an element having the minimum volume, is not lower than 1.0 and not higher than 3.5.
