Publication number: 20140129183Abstract: A method for producing a finite element model is disclosed. From a contour data set about the original contour shape of an analysis object, a nonuniformly-scaled contour data set about a nonuniformly-scaled contour obtained by anisotropically scaling up or down the contour shape is reconstructed using a scaling factor. The nonuniformly-scaled contour is divided into a finite number of elements and node points are defined to form a primary model. The primary model is anisotropically scaled by the reciprocal of the scaling factor to form the finite element model having the original contour shape.Type: ApplicationFiled: October 4, 2013Publication date: May 8, 2014Applicant: SUMITOMO RUBBER INDUSTRIES,LTD.Inventors: Ao IMAMURA, Ryosuke TANIMOTO
