| Abstract: | Based on the theory of fracture mechanics and the results of some experiments, this article discusses four typical problems in estimating the service life of sucker rods with transversal surface cracks, provides thereby scientific basis for analyzing the crack failure of sucker rods, and affords references for correct use of sucker rods, reusing of used rods, estimating of surplus life, and determination of inspection period. |
