THE EFFECT OF THE SECOND SCATTERED WAVE FOR A FINITE CRACK IN AN ELASTIC CAUSED BY DILATATIONAL WAVE

  • 摘要: 处理了无界体中一无限长、有限宽的平面应变裂纹,对任意入射膨胀波的散射问题.这里采用了Wiener-Hopf技术及标准迭代方法,得到了二次反射波到达后的应力强度因子的解析表达式,并给出了数值结果。

     

    Abstract: In the dynamic fracture field, the problem with scattered stress wave is very difficultto analyze. At present only a few analytical results have been obtained. Stephen A Than andTsin-Hwei Lu (1970, 1971) treat the transient problem of diffraction of an a plane transient SHwave and an arbitrary plane dilitational wave by a finite crack in an infinite elastic solid. Theyemploy the generalized Wiener-Hopf technique and the standard iteration method. Freund (1990)treat the analogous crack subjected to I load by...
