查询词典 tensile strain

Fracture is caused by sheet's tensile instability, Hill's totalized instability theories and Swift's diffuse instability theories which based on continuous mechanics are applied to isotropic blank; Marciniak and Kuczynski's theories are applied to orthotropic blank, which introduced thickness imperfections normal to the principal stress and strain direction as a groove pre-existing defects in the material. The stability of each part of blank at each moment is described by numerical method, and the results are shown by computer simulation, thus the fracture in sheet forming can be predicted preciously.

拉裂是由于拉伸失稳引起的，以连续体力学为基础的Hill集中性失稳理论和Swift分散性失稳理论应用到各向同性板料进行失稳判定；将Marciniak和Kuczynski的凹槽损伤失稳理论应用到正交各向异性板料拉伸失稳判定，对板料各处在成型过程中不同时刻的稳定性进行数值化描述，并运用计算机仿真技术进行直观的表现，可以准确地预测板料成型中可能出现的拉裂现象。
