Abstract:
In the present study, the distribution pattern of the ultimate tensile strength of
304-grade stainless steel was investigated using a two-parameter Weibull
distribution function. During tensile testing, it was observed that the ultimate
tensile strength varied from specimen to specimen (ranges from 878 to 1006
MPa). The results have revealed that the distribution pattern of the tensile
strength can be described by the two-parameter Weibull distribution equation.
Moreover, the fracture statistics of the stainless steel were examined by plotting
the survival probability of the specimen against the applied stress to the
specimen. It has been observed that the relationship between the survival
probability and the applied stresses can be described by the Weibull model. It
also provides design engineers with a tool that will help them to present the
necessary mechanical properties with confidence.
