Chapter A. Introduction

When performing a FE calculation of a structure, the modeling assumptions as well as the objectives must be defined. Those goals generally consist of solving:

• the displacements caused by a static loading (permanent) quasi-static (without inertial effects) or dynamic (fast-loading,)

• internal state, such as stresses, damages inflicted (cracking, etc.)

 Among the modeling hypotheses, it is preferable to handle chronologically:

• the choice of the general formulation,

• the dimensionality of the model,

• the choice of the elements,

• the definition of the interactions with the environment.
