  1. The opening stress and the life of crack growth is calculated and compared with the test results and the experience formula. the feasibility of the newman theory of opening stress used in the high strength steel is validated. then through the slice synthesis method, the three dimension surface crack of the weld joint of cone - cylinder is decomposed into many plane through cracks

    本文將基於紋閉合現象建立的帶屈服模型,用在平面貫穿紋中,計算此時的紋張開應力和疲勞紋擴展壽命,與試驗結果和經驗公式比較,驗證newman紋張開應力理論在高強鋼中的可行性;然後,用切片合成法,把潛艇結構凸錐結合殼焊處的三維表面紋分解成平面貫穿紋,用帶屈服模型的理論來分析平面貫穿紋,得到紋沿深度方向的擴展速率,進而得到潛艇結構的疲勞壽命。
