Abstract

This chapter presents a review of the major fatigue models and lifetime prediction methodologies for textile composites subjected to fatigue loadings. In this review, the fatigue models have been classified into three major categories: (1) fatigue life models, which do not take into account the actual degradation mechanisms but use S–N curves or Goodman-type diagrams and introduce some sort of fatigue failure criterion, (2) phenomenological models for residual stiffness/strength, and (3) progressive damage models, which use one or more damage variables related to measurable manifestations of damage (transverse matrix cracks, delamination ...
