Multiaxiální zatěžování a identifikace parametrů

Abstract

This diploma thesis deals with the problem of fatigue life of materials. In the beginning, categorization and description of methods designed to fatigue life prediction is done. Also their suitability for various types of loading is reviewed. In the next chapter, attention is paid to methods meant to parameters identification based on tensile test or Brinnell hardness test data. Also transformation of these parameters to their torsion equivalents accord to some strength hypothesis is done. After that, all methods are compared with each other and obtained results are evaluated. Final part of this thesis is dedicated to creation of application for fatigue parameters calculation based on methods mentioned in this thesis.
