Patent number: 8352219Abstract: The object is to enable the calculation of load transfer paths in case of distributed load applied to the structure with the numerical structure-analysis calculation system. The value of the parameter U** at each point is calculated according to the ratio of the complementary strain energy U at the application of load without fixing the point in the structure and the complementary strain energy U? at the application of load with fixing one point in the structure. In the actual calculation, according to the complementary strain energy U, and the flexibility matrix CAC with respect to the loading point A and one point C in the structure, and the inverse matrix CCC?1 of the flexibility matrix with respect to point C, and the load pA at the loading point A, the value of the parameter U** (CACCCC?1CCApA·pA/(2U)) at point C is calculated.Type: GrantFiled: February 4, 2008Date of Patent: January 8, 2013Assignee: Keio UniversityInventors: Kunihiro Takahashi, Toshiaki Sakurai, Tatsuya Nakada, Kengo Inoue

Patent number: 8239180Abstract: The purpose of this invention is to reduce the calculation time in the numerical structure analysis system based on load-transfer-path method. The parameters are set in the condition that the supporting point B in the objective structure is fixed and the load is applied to the specific loading point A. The FEM calculation means 2 calculates the deformation of the objective structure according to the structural stiffness matrix in the stiffness matrix holding means 1 to find the basic data such as the displacement of each point and so on. The FEM calculation means calculates each deformation to find the displacement under the condition that the specific loading point A and the supporting point B are fixed and three inspection loadings are applied to the variable loading point C.Type: GrantFiled: November 6, 2006Date of Patent: August 7, 2012Assignee: Keio UniversityInventors: Kunihiro Takahashi, Toshiaki Sakurai
