Abstract

This paper is devoted to study probability of survival and probability of
failure (Reliability and damage of Weibull) of steel P256 GH used generally
in pressure structures. Two statistical study are conducted the first is Student
distribution that allowed us to extract the confidence interval for the
maximum stress [469.29,473.16 ] and for elastic stress [308.66; 313.4].The
second one is Weibull distribution which identified the characteristic
elements of Weibull: the Weibull modulus m and scale factorσ0 required to
calculate material probability of survival and its probability of failure.
