Finite element method analytical manner and finite element method analytical device

摘要

Topic In extended deformation hypothesis modulo analytical precision the finite element method analytical manner which can improve is offered three prism elements by making available.SolutionsAs the finite element model of the three-dimensional structure is constructed with the multiple three-dimensional elements which include three prism elements, the same analyzing the finite element model which was constructed with finite element method, the output process which outputs the portion or all of analytical process and the aforementioned analytical value which calculate the analytical value which includes the deformation and stress of the aforementioned three-dimensional structure and, it includes. Furthermore, aforementioned analytical process uses extended deformation hypothesis modulo. At that time, concerning three prism elements to possess the paraboloidal shape which designates the line segment which ties with the point of the arm which the matrix [E] in order to obtaining the interpolation matrix [G] of the virtual strain field, the underside of the aforementioned three prism elements and each triangle of the surface, each as apex of aforementioned each triangle opposes the same each to apex as apex in order, supposing, that the bend outside the surface of same each triangle it generates, it is generated the interpolation function which can, of on the basis.
