Abstract
Engineering components often operate under alternating loads sufficiently severe to make fatigue resistance a primary design criterion. In other words, the designer must ensure that engineering components have an adequate fatigue life, which comprises both crack initiation and crack propagation period. The latter can generally be divided into short and long cracks. In proposed research project only the phenomenon of the short fatigue crack growth is addressed. The fundamental aim of the proposed project is to develop a completely new computational model to analyse the short fatigue crack growth process in mechanical elements. The model will be based on theoretical, numerical and experimental work. The new model will be appropriate for more reliable prediction of fatigue life of mechanical elements and thereafter would represent very important part of the modern design process.
