摘要
利用已得到的三维轴对称问题的非局部弹性应力的解,采用级数近似展开的方法,求解环状裂纹的边值问题。进一步阐述了用非局部理论模型求解断裂力学问題的正确性。
Solves the problem of boundary value on an annular crack by using the nonlocal stress solution of an axisymmetric crack problem and approximative method of series expansion. The result shows again the correctness of the nonlocal model for solving problems in fracture mechanics.
