本文以金属塑性成形的屈服准则为依据，提出了一种圆柱体压缩-扭转复合变形工艺，并且用塑性泥做了模拟实验。
In this paper, a compressing twisting-forging-method, based on the yield criterion, is given. It can be used for forging cylinders. The experiments are made with plasticine.
然而，国内外现有的资料大部分是关于纤维增强复合材料约束混凝土圆柱体性能研究，对于纤维增强复合材料约束混凝土棱柱体受力性能研究相对较少。
However, most information available in our country is on the study of FRP confining concrete cylinder properties, little information on the properties of FRP confining concrete prism is available.
