u3.12.01 Modelings DKT - DST - - Q4G - DKTG - Q4GG#

Summary:

This document describes for the DKT - DST - Q4G - Q4G - DKTG - Q4GG models:

  • the degrees of freedom carried by the finite elements that support modeling,

  • the related support meshes,

  • the loads supported,

  • non-linear possibilities,

  • test cases implementing the models.

They can be used for three-dimensional plate problems [R3.07.03] in linear mechanical analysis for all models and in non-linear material for DKT, DKTGet Q4GG models only. Their use for shell problems is commonly accepted considering that the plane of the element is similar to a facet tangent to the middle layer of the shell (attention, only plane facets are allowed).

Thermomechanical calculations are linked using the finite elements of thermal shells (see [U3.22.01]).
