矫直状态下钢管弹塑性变形区的研究

    INVESTIGATION ON ELASTIC/PLASTIC DEFORMATION ZONE OF STEEL PIPE BEING STRAIGHTENED

    • 摘要: 根据钢管矫直时的变形规律,通过对矫直中钢管的力学状态及矫直前后的状态参数分析,建立了一种适于现场应用的确定钢管弹、塑性变形区的新方法。

       

      Abstract: On the ground Of the deformation law of steel pipe under straightening,the author brings us an analysis regarding the mechanical condition of steel pipe being straightened and pre/post straightening conditional parameters thereof as well,resulting in a new approach to on-the-site determination of the said steel pipe elastic/plastic deformation zone.
