    摘要： When discretizing an analysis target part into plural elements and performing analysis, sheet thickness reduction rate or maximum principal strain at an equivalent position including a same element is compared by either a manner of combining two adjacent elements after the analysis or a manner of changing an element discretization size with two types and performing the analysis, and the element where the difference is large is extracted as a fracture risk portion.With this structure, a fracture risk portion can be extracted reliably when a fracture is predicted by a finite element method.

    摘要： A metallic hollow columnar member with a polygonal cross-section having at least five vertices and sides extending between the vertices, is disclosed. The polygonal cross-section is divided by two vertices (A, B) with small inside angles into two perimeter segments with a perimeter comprising one or more sides, and at least one of the two perimeter segments contains at least four sides. The respective inside angles of at least three vertices (V(i)) included in the perimeter segment which includes the at least four sides are equal to or less than 180°, the distance (SS(i)) between each of the at least three vertices (V(i)) and a straight line (L) connecting the two vertices (A, B) is shorter than ½ of the distance between the two vertices (A, B), and the inside angle of the vertex (C) with the smallest inside angle among the at least three vertices (V(i)) is larger than the inside angles of the two vertices (A, B). Vertices (VI) are present on the perimeter segment including the at least four sides, respectively between the vertex (C) with the smallest inside angle among the at least three vertices (V(i)) and one (A) of the two vertices (A, B), and between the vertex (C) with the smallest inside angle and the other (B) of the two vertices (A, B), said vertices (VI) having inside angles larger than the inside angle of the vertex (C) with the smallest inside angle.
