中文摘要:冲击力场中,在材料冲击面上的压强近乎无穷大,韧性来源于材料的局部位移.理论上能提高材料局部快速位移的手段都能提高材料的韧性.对于所有以颗粒形式增韧的体系,颗粒和基体之间形成弹性过渡区,从而实现'破裂-下楔-压缩-应力方向改变'是增韧的基本模式.
外文摘要:Under the impacting stress, the pressure on the surface of t he bulk is almost infinite and toughenment is based on the localized displacemen t of material. Any material can be toughened by the measurement that enhances th e shift ability of the sample. Between the particle and the bulk, transition are a is critical in the particle toughening system, and a new mechanism is postulat ed “cracking_wedging_compressing_altering the direction of the impacting force' , which can explain all the phenomena in the experiment.
