Application of crack stoppers in the ramp structure

Abstract

The presented Master’s degree work aimed on the extension of the early proposed approach to the study of fatigue control of metals. For this purpose, some finite element modeling was performed. In the researchers conducted by the Aircraft Structure Department at National Aviation University the possibility to assess the special fatigue testing machines has been proved. The work investigates the influence of crack stoppers applying to the structure. The scientific value of the presented work is as follows: prevention of crack propagation in places of restrained access, increasing of structure life time. The practical value of the work is determined by possibility to use the practical knowledge in further implementation of crack stoppers in material behavior control. It is recommended to use the results of the master's work in the study of crack propagation control and the crack initiation by means of crack stoppers implementation.
