3.8.14. Rectangular plate

Table 3.17 shows key features of the base element (shell).

Table 3.17
Fig. 3.48. Rectangular plate: LCS and fixing conditions
 
Feature Description
Reference points:

A: bottom of side walls.

Local shell coordinate system (LCS):

Axis X: transverse axis of plate;

Axis Y: transverse axis of plate;

Axis Z: normal axis to plate.

Orientation in WCS:

All axis can be horizontal and vertical according to the shell options:

Additionally, can flip the element relative to its plane to simulate the bottom plate of the pressure vessel.

Shell constraints (dof):

Point A.

All calculations by the finite element method (FEM) fix bottom of side walls.

Shell loads:

Inner overpressure.

Outer pressure.

Hydrostatic pressure.

Thermal strains.
