Some pitfalls of S-N curve fits and rough construction of its tolerance bands
Original language description
S-N curve is in this time of deep studies of fatigue mechanisms quite out of the interest of materials scientists, but for design engineers it is still very useful tool. Its assessment need not be trivial task if certain reliability is asked. Even the choice of dependent and independent variable in regression need not be fully self-evident for very large and along S-N curve changing dispersion and for the asymptote(s) of S-N curve perpendicular to stress axis. The contribution tries to choose suitable regression function containing regression parameters with clear and definite meaning. It presents very rough but for basic use sufficient presentation of reliability of S-N curve assessment, which can be performed and understood also by non-specialists inmathematical statistics and without necessity of special software.
