Abstract

In this article the results of numerical experiments of calculation of stress intensity factors (SIF) for typical aviation structures with cracks are presented. The results obtained were used while creating database for parameters, which affect on SIF, for the damage tolerance value to be evaluated. Parametric calculations, accomplished in this particular work, enable us to evaluate SIF for typical aviation structures with cracks with various characteristics. The usage of the results obtained allows to accelerate and unify definition of crack growth rate, gives the opportunity for specialists who aren't familiar with finite element method to accomplish damage tolerance calculations.

Keywords:
