摘　　要：在管材成形力和行程的关系曲线基础上 ,提出了用反算法确定管坯的塑性本构关系。开发了确定塑性本构关系参数的反算程序 ,并结合单向压缩实验对薄壁管 LF2 M-32× 1的材料性能进行了研究 ,获得该管坯的本构关系。Based on the curve of load displacement of tube deformation,a reversion calculation method is put forward to get constitutive stress strain relationship and a related computer program is developed to determine the parameters. Material properties of thin walled tube LF2M 32×1 have been studied using reversion calculation and through axial compressing experiments, resulting in gaining the constitutive stress strain relationship of this tube.
