Stochastic Cumulative Models for Fatigue
This chapter is devoted to modelling of fatigue crack growth via cumulative jump stochastic processes. A wide class of such processes can be represented in the form of a stochastic integral with respect to counting Poisson measure in particular, such proc

PREFACE
Fatigue fracture of engineering materials has been recognized as an important cause of failure of such engineering
struc~ures
as: aircrafts, vessels, road vehicles, cranes etc.
However,fatigue is a very complicated process that is difficult for accurate description and prediction. Because of the inherent randomness found in fatigue data it is no doubt nowadays that a fatigue of real materials should be regarded as a random phenomenon and analysed by use of the stochastic theory. Today, the stochastic approach to fatigue is perceived as important and challenging task in mechanics and structural/mechanical
reliability.
The CISM course and the presented volume of the lecture notes have been intended to summarize the latest achievements in stochastic modelling and analysis offatigue. The lectures cover all main aspects offatigue, namely: methodology of stochastic modelling of fatigue, tools for characterization of random fatigue loads, physical and mechanical aspects of stochastic fatigue crack growth, basic stochastic models for fatigue and the estimation of fatigue reliability of specific structural systems. The proposed lecture notes should be of interest to engineers and researches in industry and at universities who want first-hand information on the present status and trends in this rapidly developing field of engineering scienc
