In this paper, the finite element method for U shape yieldable steel ribs is presented.
本文提出采用有限元法对U型钢可缩性支架进行计算。
Results show that the primary cause to the laminar defect of the umbrella bone steel in the process of cold bending to U-shape is the severe carbon segregation in the steel band.
结果表明，钢带中部严重的碳偏析是导致在冷弯成U形伞骨时，形成钢带分层的主要原因。
