3. Consideration of stresses of varying amplitudes

3.1 Introduction

Estimating the fatigue behavior of components or structures in service is a problem that requires a multidisciplinary response, taking into account the type of cyclic loading. Generally speaking, such loading corresponds to stresses of varying amplitudes .

Different approaches can be used, depending on our knowledge of the structure under consideration, the loads in service and the type of equipment available for testing.

The aim of this chapter is to describe...
