A GENERAL SOLUTION OF THE PLANE STRESS PROBLEMS IN PIEZOELECTRIC MEDIA WITH LINE CRACKS

  • 摘要: 研究了含直线裂纹系的压电材料平面应力问题单个裂纹和双裂纹问题的封闭解答表明,在裂纹尖端,应力、电场强度和电位移有1/2阶的奇异性并与前人结果比较了产生电场奇异性的物理因素

     

    Abstract: Considering continuous boundary condition of electric field at the cracks, a general solution of the plane stress problems in piezoelectric media with line cracks is provided by using function of complex variable and solving Riemann-Hilbert problems Solution in closed form and field intensity factors are given for problems of a single crack and two cracks It is shown from the solution that the stresses and electric field intensity and electric displacement have (1/2) type of singularity at the crack tip...
