u3.11.04 Modelings POU_D_TG, POU_D_TGM

Summary:

This document describes for POU_D_TGet POU_D_TGM 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

Modeling POU_D_TG corresponds to a formulation of Timoshenko beam elements taking into account a modeling of the warping of the section (cf. [R3.08.03]).

Modeling POU_D_TGM is based on the same formulation and makes it possible to take into account non-linear multi-fiber behavior.

They can be used for beam problems in isotropic linear mechanical analysis and in elastoplasticity.
