| Abstract: | The outer bottom of an oil tanker is taken as an example,the difference between membrane stress and bending stress of a shell plate element is analyzed in the direct calculation of the tanker's stiffened shell plate structure.It could be concluded that the membrane stress at the centroid of the element should be taken as working stress for estimating the strength of shell plate structure of a ship. |
