**v2.08.012** FORMA12 — Practical work from the "introduction to linear & non-linear dynamic analysis" training course
====

**Summary:**

This case is an introduction to using Code_Aster for dynamic transient analysis (linear and non-linear). It treats a thick steel plate, subject to sinusoidal excitation on a vibrating table.

The plate is modelled in 3D elements. Transient analysis on a modal basis is compared with a direct transient analysis. In the last part, the plasticity of steel is taken into account by a non-linear law.

The various models discussed are:


*   modeling A: modal analysis;


*   B modeling: direct transient;


*   C modeling: transient on a modal basis with static correction a priory;


*   D modeling: transient on a modal basis with a posteriori static correction;


*   E modeling: non-linear transient;


*   F modeling: linear transient with contact nonlinearity;


*   G modeling: non-linear transient by dynamic substructuring.

The first chapter introduces the geometry and data common to all models.
