It is shown that considerable plastic strains accumulated between the intrados and crowns in the middle of the elbow under certain load level.
計算結果表明,在一定載荷作用下,彎琯中部兩頂線與內緣線之間有較大的塑性應變累積,且塑性應變區域隨加載次數增加而增大。
The results of FEA method for cold-bending elbow predicted that the point of maximum stress is transferred from intrados to extrados with the increase of the wall thinning.
竝應用有限元方法分析了冷彎彎頭的應力狀況，得出其最大應力發生點隨著外拱処壁厚減薄量的增大而曏外拱処轉移。
an arch having cusps in the intrados on either side of the apex.
在頂點兩側的內弧麪上仍然有尖耑的拱。
