Fatigue of fiber reinforced composites under multiaxial loading

This chapter is a revised version of Chapter 10, Fatigue of fiber reinforced composites under multiaxial loading by M. Quaresimin and R. Talreja, originally published in Fatigue Life Prediction of Composites and Composite Structures ed. A. P. Vassilopoulos, Woodhead Publishing Limited, 2010 (ISBN 978-1-84569-525-5). 

In the attempt to provide a contribution to this area and to draw the lines of future research activities, this chapter presents an overview of the multiaxial fatigue

In general, fatigue results are generated under sinusoidal loading conditions, where the time variation of the three stress components is given by 

to measure the degree of multiaxiality of the external loads, one can introduce the biaxiality ratios calculated from the amplitudes of the geometrical stress components
