Fatigue Damage Modeling Techniques for Textile Composites: Review and Comparison With Unidirectional Composite Modeling Techniques

Abstract

Composite structural parts have been successfully introduced in high performance industries. Nowadays, also lower performance, high volume production industries are looking for the application of composites in their products. Especially attractive are textile composites (woven, braided, etc.) because of their better drapability and higher resistance to out-of-plane and dynamic loads. Currently, however, extensive mechanical tests are needed to properly design a composite structure. This is a requirement the large volume industries typically do not have the resources nor the time for. Reducing the need for structural tests can only be done if reliable simulation techniques are available. Simulation techniques for fatigue loading are particularly interesting because products generally have to perform their function over a period of time. For the textile structural composites concerned in this paper, some notable modeling techniques have been developed over the past 15 years. These techniques are presented here and the state of the art is established together with insights for future development by comparing the state of the art with the modeling techniques for laminates from unidirectional (UD) laminae.

Experimental Studies of Stiffness Degradation and Dissipated Energy in Glass Fibre Reinforced Polymer Composite under Fatigue Loading

“…The residual stiffness degradation of FRP composite subjected to fatigue loading at various R-ratio need to be quantified and the appropriate parameters should be identified from a series of tensile and fatigue tests and for prediction of the residual stiffness for the laminates [9]. The past studies have shown that the fatigue behaviour of composites is highly dependent on the stress ratio R and the frequency of applied cyclic loading [10,11,12,6,13].…”

Structural health management utilization for lifetime prognosis and advanced control strategy deployment of wind turbines: An overview and outlook concerning actual methods, tools, and obtained results

“…Sevenois et al [28] review existing fatigue damage modeling techniques for composite materials deployed over the last 15 years. In [28], the discussion about existing fatigue models is carried out through model classification in four groups, namely: "fatigue life models", "residual strength models", "residual stiffness models", and "mechanistic models" [28].…”

“…In [28], the discussion about existing fatigue models is carried out through model classification in four groups, namely: "fatigue life models", "residual strength models", "residual stiffness models", and "mechanistic models" [28]. Judging on [28], fatigue life models are used to predict remaining useful lifetime (RUL) using life cycles, stress, and laminate stiffness relations often achieved through the experiments.…”

Contrary, residual stress models relate to prediction of residual strength, while residual stiffness models' are also concerned with the prediction of deformation of the structure during fatigue process and the resulting stress redistribution' as stated in [28] (that are in the basis statistical and probabilistic models).…”

Modelling of Damage Evolution in Braided Composites: Recent Developments

“…Therefore, some of those methods were difficult to extend to textile composites because of their different structures and failure modes. For braided and woven composites, comprehensive literature reviews (Xu, 2011;Sevenois and Van Paepegem, 2015;Wang et al 2015) unveiled that considering appropriate damage mechanisms was the key issue for analysis of textile composites subjected to fatigue. The entire fatigue process can be divided into different stages, and each stage involves distinct damage modes.…”
