剪切带状分叉

SHEAR-BAND BIFURCATION

  • 摘要: 本文从扩散型解法出发,结合实验,揭示了剪切带状分叉的主要特征;进而,论述材料分叉与结构屈曲(分叉)的不同之处。文中结果表明:在诱发剪切带过程中,材料内空洞的激化速率是控制因素而不在于空洞体积比的自身数量。
    Abstract: A diffuse type of theorctical solution,interrelatedwith experimental ob-servations?is given to reveal the characteristics of shear-band bifurcation. This effort is usedto distinguish material bifurcation from structural buckling(bifurcation).It is demonstratedthat the rate of porosity development is governing the process of shear banding,instead ofattributing to the amount of porosity itself.
