J Estimations For Axial Surface Cracked Pipes Under Pressure

축방향 표면균열이 존재하고 내압을 받는 직관의 J 예측 방법

In the present paper, limit pressures for axial surface cracked pipe are proposed, and a reference stress based J estimation method is also provided based on the proposed limit pressure solutions. Employed cracks are assumed to be constant-depth, internal surface cracks, and wide ranges of variables are considered.
