ON THE STRESS DISTRIBUTION AT THE BASE OF THE FRONT CORNERS OF ACCOMMODATION STRUCTURES

The accommodation structure of a ship is generally arranged at the stern. Longitudinal bending moments give little effect there. However, corners of the fore end where the accommodation structure is connected with the main hull are still subjected to high concentrated stress due to discontinuity of the structure. Though the rounded corner of the fore end wall is known to relieve the stress, a right-angle structure has lately been adopted, mainly for the convenience of work, but it has caused damages to the front corners on several ships. To clarify the relations between the corner shape and stress distribution by the longitudinal bending of the ship, a study is made of eight types of corner shape by finite element method. The results have shown that the maximum stress decreases by 40 percent on rounded corners from that on right-angled corner. It is also found that the knuckle type corner with straight line is as effective as the rounded type in relieving stress. The availability of longitudinal and transverse brackets for right-angled structures and the relations between bracket size and the degree of stress relief are also investigated.
