4. Example of use

For the use of RECA_WEIBULL, we can refer to the SSNA103 [V6.01.103] test case.

It is an axisymmetric modeling of a cylindrical specimen (length of 407 mm and radius of 68 mm) subjected to traction. Example of resetting the parameter \({\sigma }_{u}\) of the Weibull method by the linear regression method on three bases of results corresponding to distinct temperatures (the Weibull module \(m\) is fixed and equal to 24).

Results:

At the end of the calibration, the result table gives for each Weibull constraint, the experimental and theoretical failure probabilities as well as for each temperature T associated with a results base, the Weibull module \(m\) selected and the cleavage constraint \({\sigma }_{u}\) reset.
