Sažetak:
The influence of stresses resulting from weld misalignment in cylindrical shell circumferential weld joint on the shell integrity has been considered. The stresses have been estimated analytically by API recommended practice 579 procedure and calculated numerically by using of finite element method. Surface circumferential crack could appear perpendicular to the principal stress at the location of maximum stress. Failure assessment procedure has been performed for the most dangerous situation (e = 8 mm) varying the crack depth to thickness ratio as a/t = 0.4 ; 0.45 and 0.5. Critical internal pressure values for these cases have been found by using of FAD diagrams.
