**u2.02.02** Instructions for using elements TUYAU_ *
======================================================

**Summary:**

This document is a user manual for models TUYAU_3M and TUYAU_6M.

The finite elements TUYAU_3M and TUYAU_6M correspond to linear elements of straight or curved pipes. Element kinematics TUYAU combines both beam kinematics, which describe the overall movement of the pipe line, and shell kinematics, which describe the swelling, ovalization, and warping of the cross section.

These models can be used for problems with relatively thick three-dimensional pipes, in linear or non-linear mechanical analysis and in small displacements.
