| Description
| - Tzv. Nagsrova rovnice zharnuje velimi dobrý popis křivky růstu únavové trhliny. V roce 1999 první autor tohoto článku publikoval velmi podobnou rovnici, která je určena pro dané asymetrické zatížení s kladným poměrem R obsahující stejné prarametry se stejným významem jako v nasgrově rovnici. Ve většině následných studiích tohoto autora tato rovnice vedla k lepší aproximaci než nasgrova rovnice. (cs)
- The so-called NASGRO equation allows a very good description of fatigue crack growth curves, i.e. the dependence of crack length increase per one fatigue cycle da/dN on the stress intensity factor range delta K. In 1999 the first author of this paper published quite similar equation, which written for given loading cycle asymmetry with positive stress ratio R contains the same parameters having similar meaning as in the NASGRO equation. In most cases studied by the authors this equation leads to a better fit than the NASGRO equation, above all when the experimental curve contains relatively long Paris straight line and/or relatively sharp bend from this line to the threshold stress intensity factor range. The generalization of the NASGRO equation for various values of stress ratio R was made in a quite complicated way. The new equation was generalized using the Walker model based on the relation delta K(R) = delta K(0)(1 - R)-m which is valid also for threshold value delta Kth but not for critical str
