Static behaviour of rectangular plate

The dynamics of a rectangular plate can be predicted quite well with shell (coque_3d) elements. I also liked to know the accuracy of the displacements for this kind of structures. A comparison between solid elements and shell elements has been made.

Dimensions and boundary conditions of the plate The length and width of the plate are 1*1 m. The thickness of the shell elements has been increased to 0.02 m to enable meshing with solid elements (tetrahedrons and hexahedrons). Two types of boundary conditions have been given:

  1. clamped at the four sides (all displacements and rotations are suppressed)
  2. clamped at one side (all displacements and rotations are suppressed)
