“…However, investigations have shown that strain in the matrix is the key factor influencing the fatigue behavior. 435 All these factors require additional considerations compared to traditional materials, 436,437 which impose the necessity to use different design methods to predict the fatigue life of composites. 438 With respect to repetitive loads, up to 10 million cycles within the overall life of a structure are to be considered.…”

Currently, the application of pultruded profiles is increasing owing to their advantages, such as light weight, high strength, improved durability, corrosion resistance, ease of transportation, speed of assembly, and nonmagnetic/nonconductive characteristics. This review analyzes the main application fields of elements produced by pultrusion manufacturing processes: bridges and bridge decks, cooling towers, building elements and complete building systems, marine construction, transportation, and energy systems. Analysis of the scientific literature in relation to the mechanical behavior of pultruded elements is presented as well. Finally, this review outlines the future study possibilities, giving the researchers and practitioners the directions for deeper investigation of specific features and exploration of new ones concerning the mentioned aspects of pultruded fiber-reinforced polymer composites.

“…Therefore, in order to avoid self-heating or at least to minimize its influence, various approaches were applied. In many cases, the loading frequency was significantly decreased (see e.g., [119]), which allows for the neglect of the self-heating effect, while another approach was based on cooling the surface of a tested structure subjected to fatigue loading [44,46,50,120,121]. The self-heating effect, however, can be utilized for the material characterization and diagnostic problems of polymeric and PMC structures.…”

The self-heating effect is a dangerous phenomenon that occurs in polymers and polymer matrix composites during their cyclic loading, and may significantly influence structural degradation and durability as a consequence. Therefore, an analysis of its criticality is highly demanding, due to the wide occurrence of this effect, both in laboratory fatigue tests, as well as in engineering practice. In order to overcome the problem of the accelerated degradation of polymer matrix structures, it is essential to evaluate the characteristic temperature values of self-heating, which are critical from the point of view of the fatigue life of these structures, i.e., the temperature at which damage initiates, and the safe temperature range in which these structures can be safely maintained. The experimental studies performed were focused on the determination of the critical self-heating temperature, using various approaches and measurement techniques. This paper present an overview of the research studies performed in the field of structural degradation, due to self-heating, and summarizes the studies performed on the evaluation of the criticality of the self-heating effect. Moreover, the non-destructive testing method, which uses the self-heating effect as a thermal excitation source, is discussed, and the non-destructivity of this method is confirmed by experimental results.

Fiber reinforced polymer (FRP) composites have been used in industries such as aerospace, marine transportation, and wind energy for several decades prior to attracting widespread attention for applications in civil engineering. While limited data is available on the long term fatigue performance of FRP materials for construction projects, it is worthwhile to review the extensive work done in other engineering disciplines and consider the lessons learned. In particular, the probabilistic nature of the fatigue life of composite materials under cyclic stresses has been captured by various models presented in literature; although the contextual parameters may differ, their use may extend to other applications. In this work, the Sendeckyj wear-out model based on the strength-life-equal-rank assumption is applied to fatigue data from a variety of material types and configurations intended for building projects. The results presented show that the model is versatile and can be calibrated to describe the probabilistic nature of both the static and fatigue response of FRP composite materials for various applications.
