“…When full-scale structural components are subjected to in-service fatigue loadings, stiffness is a very adequate parameter, as it can be measured nondestructively, and the residual stiffness exhibits much less statistical scatter than residual strength (Hashin, 1985;Highsmith & Reifsnider, 1982;Kedward & Beaumont, 1992;Whitworth, 2000;Yang, Jones, Yang, & Meskini, 1990;Yang, Lee, & Sheu 1992).…”

“…The material stiffness decreases with every increasing load cycle, and failure occurs when the damage parameter (D), which is based on the changing stiffness value, is unity. Similar residual stiffness models were proposed by Whitworth [16], [17] and Yang et al [18], [19] for unidirectional composites. Hansen [20] and VanPaepegem and Degrieck [21] employed similar stiffness degradation models for woven composites and implemented them into finite element analysis models.…”

Abstract. Due to the increased use of composite materials in the aerospace industry, numerous attempts have been made to develop fatigue models in order to predict the fatigue behaviour and consequently the fatigue life of these materials. Existing fatigue models have significant deficiencies, thus are not widely acceptable in the industry. A better understanding of the exhibited fatigue behaviour of composite materials is consequently required. The complex nature of fatigue behaviour in fiber-reinforced composite materials is presently investigated. An explicit progressive damage model, that is mechanistic in nature, is currently being developed using the concept of a representative volume element. A micromechanical finite element model that is capable of explicit damage initiation and propagation modeling is utilized for simulation of damage development. The predicted numerical results illustrate the capabilities of the current model. Future work is also outlined in the paper as the development of the fatigue model is continued.

“…e residual strength is one of the most important properties of composite materials under the fatigue loading and is the basis of cumulative damage assessment and fatigue life prediction [8,9]. In GFRP, fatigue damage initiates and propagates during cyclic loading, where several types of damage may exist physically at one time or another which in addition may be different during different periods.…”

“…In this paper, residual ultimate bearing capacity of the specimens after the fatigue test was obtained in the form of axial compressive ultimate bearing capacity, and the residual strength of specimens after nth loading cycle can be modified and expressed in (4) and (5) based on the existing theories [9,30,34,35]:…”

“…For instance, Hashin and Rotem [5,8] developed a fatigue failure theory based on the Hashin-Rotem static failure criterion, which has been applied to predict the fatigue failure of angle-ply laminates. Yang et al [9] and Shokrieh and Taheri-Behrooz [12] proposed methods of fatigue life prediction based on the modulus reduction and energy dissipation, respectively. Abo-Elkhier et al [17] investigated the fatigue life of GFRP composites using modal testing, which indicates that the changes of modal parameters provide a proper method for predicting the fatigue behavior of composite structures.…”

To overcome the fatigue safety problem of transmission tower cross arms caused by the wind-induced vibrations, an experimental study on the high-cycle fatigue performance of a new type of GFRP-steel sleeve composite cross arms was carried out. A total of six specimens were subjected to 500 thousand cyclic loadings based on the practical engineering background. e stress state was monitored, and a variety of load-displacement-time curves, the energy dissipation capacity, and the dynamic strain were analyzed to examine the effects of fatigue loading. After the fatigue test, the specimens without significant fatigue failure were evaluated to derive the residual bearing capacity. Based on the residual strength theory, the cumulative damage was examined, and the fatigue life was predicted under various loading conditions to ensure the reliability of composite cross arms. It is shown that the new type full-scale GFRP-steel sleeve composite cross arms can demonstrate a high level of safety redundancy on antifatigue performance and can be expected for wide application in power transmission towers.
