A plate

Plates represent important load-carrying parts of the ship hull. Plates differ from shells in the way they take loads. Plates are loaded in such way that they have deformations out of their own plane. These deformation can be attributed to lateral forces or forces along the plate's edge.

A plate's stiffness properties depends on the plates geometry. Especially the relationship between thickness and the plates extended area in the x-y-plane is important. We therefore separate between three main plate types:

  • Thin plates with small deformations - 1. order plate theory

  • Thin plates with large deformations - 2. order plate theory

  • Thick plates - not dealt with here
