“…It was also shown by Portemont et al. 29 that the matrix cracking and damage in the joint were rate-dependent. Therefore, as the strain rate was increased, the initiation of matrix cracks was delayed.…”

In the present research, effects of applying strain rate on the mechanical behavior of single-lap glass/CNF/epoxy composite bolted joints including, damage initiation bearing stress, 2% offset bearing strength, ultimate bearing strength, bearing chord stiffness, ultimate bearing strain, and energy absorption were studied. To this end, a comprehensive experimental program was conducted. The protruding head bolt was used, the clearance was considered to be near fit and a finger-tight bolt condition was applied to all joints. The dimensions of joints were chosen to promote the bearing failure mode based on the ASTM standard. Four types of single-lap bolted joints (SLJs) with lay-ups of [–45/0/45/90]s and [90/–452/45]s with and without CNFs were tested at strain rates in the range of 0.0048 s−1 to 0.89 s−1. Unlike the available experimental results, the results obtained by the present experiments showed that the strain rate has a significant effect on all the above-mentioned mechanical parameters of SLJs. Also, it was shown that employing CNFs improved the mechanical parameters of SLJs under quasi-static and dynamic strain rates.

“…The fields of the apparent temperature variation are obtained by computing the difference of two temperature fields between a time 𝑡 and the time 𝑡 0 which corresponds to the beginning of the loading of the sample. This analysis methodology is classically used by various authors to focus on temperature variation due to the mechanical loading of the sample (Meola and Carlomagno 2009;Portemont et al 2018). At the beginning of the test, the abscissa within the intervals 𝑥 = [0; 60] and 𝑥 = [265; 320] refer to the tabs length.…”

In this study, the rate dependency of transverse cracking evolution in cross-ply laminates is investigated for several 90° plies thicknesses. The crack detection methodology is based on a recently proposed protocol relying on the use of infrared thermography. A new analysis methodology is proposed to make it more robust and to directly link the spatial localization of the crack with the stress level at which it occurs. Based on this methodology, the results obtained for various loading rates and 90° ply thicknesses are analysed. The crack density evolution with respect to stress apply to the laminate exhibits a rate dependency only for the [0/90]s configuration. This rate dependency is finally discussed based on transverse crack onset theories in cross-ply laminates.

“…There is a growing use of polymer composites as primary aerostructures, with recent aircraft such as Boeing Dreamliner and Airbus A350 having more than 50% of the vehicle weight as polymer composite [1], [2]. Other sectors, such as automotive, marine, and infrastructure are now widely adopting these materials.…”
