複合体の有限要素モデル作成方法及び装置
Document Type and Number:
Japanese Patent JP4750984
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To increase the analyzing accuracy of a composite body. SOLUTION: In this method of manufacturing a finite element model of the composite body, the finite element model Fa for analyzing the numerical values of the composite body is formed of the composite body F formed by covering a cord arranged body 9 having a cord c arranged thereon with a rubber g. The method comprises the steps of modeling the rubber g with a solid element e1 and modeling the cord arranged body 9 with a film element e2 for which anisotropy with different Young's moduli is defined between the longitudinal direction j of the cord c and a direction k orthogonal to the longitudinal direction j. At least the Young's modulus of the film element e2 in the longitudinal direction j of the cord comprises the Young's modulus for compression used for calculation when a compressed stress acts thereon and Young's modulus for tension used for calculation when a tensile stress acts thereon. The Young's modulus for compression is made smaller than the Young's modulus for tension.
