Title: Castillo Estimation of Tolerance Bands of S-N Curve and Its Modifications
Author(s): Jan Kohout               

Abstract: A precise determination of tolerance bands of S-N curves is quite a difficult problem; therefore simple approximate constructions of these bands are often used. Castillo et al. suggested a sophisticated and at the same time easy procedure for their estimation which, however, needs a special type of regression function for describing S-N curve. This type of regression function called the Castillo function is suitable only for high-cycle fatigue region close to fatigue limit. The paper focuses on other regression functions used in the Castillo procedure, namely on the Kohout and Věchet function and the Stromeyer function.

Keywords: S-N curves, Stromeyer function, tolerance bands.
