Description :
_____________
This procedure enables the user to calculate the limiting state for
a structure due to a fatigue test. The method which is used in the
procedure is based on ZARKA's method.

TBZA : TABLE type object containing the following datas

TBZA.SIG1 MCHAML these elastic stresses correspond to
TBZA.SIG2 the extrem stresses of the loading
cycle.
They must be calculated out of the
procedure before starting @ZACPLUS. We
suppose that the loading cycle
depends on one parameter only.
So, the elastic answer will be :
SIG elas = (1 - F)*SIG1 + F*SIG2
(F is a periodic function with 0
