v6.01.103 SSNA103 - Weibull model parameter calibration

Summary:

This test validates the RECA_WEIBULL command allowing the identification of the parameters \(m\) and \({\sigma }_{u}\) of the Weibull model.

The identification is carried out using a database consisting of 45 tests, all carried out on smooth cylindrical specimens at three different temperatures, \(-150°C\), \(-100°C\) and \(–50°C\). This database is obtained by random drawing a representative sample of the Weibull statistical law corresponding to values of \(m\) and \({\sigma }_{u}\) set arbitrarily.
