屈服应变 meaning in English

yield strain

The parameters are measured respectively during the experimental process , such as bearing capacity , deformation , strain and so on . it concludes that when the other conditions is equal , the limit bearing capacity of the concrete filled steel tube long column subjected to axial compress is reduced along with the long diameter ratio increased
从试验结果可以看出：钢管混凝土轴心受压长柱的稳定承载力，在其他条件相同时随长细比的增大而逐渐降低；试件在最大承载力状态下，钢管表面的平均纵向应变已超过钢管的屈服应变值，破坏呈现为非弹性失稳破坏。
In this paper , the ductility of steel bar is expressed by ductility ratio b , the figure of dividing ultimate strain by yield strain . the ductility of section is expressed by ductility of section ratio , the figure of dividing ultimate curvature by yield curvature . the displacement ductility is expressed by displacement ductility ratio , the figure of dividing ultimate displacement by yield displacement
论文中钢筋延性采用钢筋延性比b来表示，即极限应变与屈服应变的比值；构件截面延性采用截面延性比来表示，即极限曲率与屈服曲率的比值；构件位移延性采用位移延性比_来表示，即极限位移与屈服位移的比值。
