    • Abstract
  • A three-dimensional problem of disk crack of type I is studied according to the theory of nonlocal elasticity in this paper.The influence function of the axisymmetrical problem is given,and dual integral equations of the problem are derived.An effective method is devised to deal with the nitegral equation of unbounded kernels by changing the unbounded kernel into bounded ones.The nUmerical solution of stress field at the adge of disk crack is presented,it is found that no stress singularity is present at the acrck tip.The.;value and distribution of stresses at.the crack tip are also studied in the paper.
