Abstract
During designing it is important to be able to know as accurately as possible the
entire service life. In this case the model of initiation and growth of short cracks as
well as model of growth of long cracks are important. From the theory it is known
that the defects, i.e., the cracks causing destruction or fracture of the basic function of
the individual components, spent almost 80 - 90 percent of the entire service life in
micro conditions, i.e., in conditions in which they cannot be detected by standard
non-destructive methods. Therefore it is very important to have as precise
computation models for determination of the service life. For this area we used Bilby,
Cottrell and Swinden model which is based on the theory of continuously distributed
dislocations. In the presented work the model is complemented with random
generation of structure of material before cracks. Such a model is i
