Code_Aster is a code general practitioner for the study of the behavior structural mechanics.
The
priority scope of application is that of the mechanics of deformable
solids: that justifies the number of functionalities attached to the
mechanical phenomenon. However, the study of the mechanical behavior of
the industrial components requires beforehand the modelization of the
stresses to which they are subjected, or of the physical phenomena which
modify the parameters of
this behavior (fluid offsite intern or,
temperature, phase change metallurgical, forces of electromagnetic
origin...). For these reasons, Code_Aster
offers several
possibilities of “sequence” of the mechanical phenomenon with the
thermal or the acoustics, or with of other software, as well as a “kit”
of construction of problems thermo-hydro-mechanics coupled.
Although
Code_Aster can be used for many problems of structural analysis (code
general practitioner), it was developed in particular to allow the study
of the components of materials or machines used in the field of the
electricity production and transmission. Thus the priority was given to
the modelization of metal structures, géomatériaux and the reinforced
concrete structure components.
One will find very few modelizations available for composites or elastomers.
The nonlinear analyses, as well in mechanics as in thermal, are in the middle of
Code_Aster
: their effective drug required the tuning of powerful and relatively
simple algorithms of use, even if the goal is not to make them function
in “black box”. For the complex studies, it is thus necessary to
understand the nature of the operations carried out by the code, in
order to be able to control them in
an optimal way: one refers then
to the theoretical notes giving the details of the modelizations and the
methods, gathered in the Reference material.
