N metallic materials - sheet and strip - determination of tensile strain hardening exponent n - values 金属薄板和薄带拉伸应变硬化指数
Iron and steel - method of determination of the tensile strain hardening exponent n of steel sheet and plate 钢铁.薄钢板和钢板拉伸应变硬化指数n的测定方法
By analyzing the simulation results , how the hardening parameter , bend radius parameter and thickness parameter influence springback is studied 通过对模拟结果的分析,研究了硬化指数、弯曲半径、材料厚度等因素对回弹的影响规律。
