Abstract This study, for the first time, presented a novel Bayesian inference deep learning model based on dilated convolutional ResNet framework, utilizing acoustic emission (AE) signals as inputs to quantify uncertainty of compression after impact (CAI) strength in composites. The output included mean CAI and predictive aleatoric uncertainty. epistemic was estimated by randomly sampling input multiple times. AE were divided into complete training dataset partially missing investigate data...
Carbon fiber-reinforced polymer (CFRP) has become widely applied in engineering fields such as aerospace and the automotive industries. Evaluating damage tolerance of CFRP with manufacturing defects under impact loads is crucial ensuring reliable service components. In this study, four types wrinkle are designed, effect mechanism thoroughly discussed, focusing on compressive response. The results indicate that primarily affect response via fibers being subjected to stress concentration....
This paper investigates the effect of Ø 0.11 mm Z-pinning on structural properties composite T-joints via ultrasound-guided insertion process. The joints are determined by stiffener web pull-off testing. experimental results show that carbon Z-pins exhibit a better improvement than steel due to interface between and laminate owning higher pullout strength. When skin-flange area is inserted with 0.2 vol% Z-pins, peak load total energy absorption capacity can be improved 72.4% 436.5%,...
Abstract Nowadays, fracture characterization of dissimilar materials adhesively bonded structures still generally refers to standards for fiber‐reinforced plastic composites. Moreover, the calculation methods energy release rate specified in these often lead great deviation due differences material properties and geometry. In this paper, corrected beam theory with effective crack length (DM‐CBTE) method mode II was proposed. The geometry as well effect clamp were all considered. experimental...
The formation of strain-induced martensite (SIM) is found in metastable austenitic stainless steel (m-ASS) during cold forming, and the presence SIM may cause reductions toughness, ductility, corrosion resistance m-ASS. These mechanical properties can be restored improved by proper heat treatment after however, which obviously raises manufacturing costs. One low-cost way to reduce amount m-ASS forming maintain temperature at an appropriate level. This paper intends investigate approach...
Abstract The investigation on fracture test methods for dissimilar materials adhesively bonded structures is urgent. In this study, three mode II composite‐titanium are experimentally and numerically studied. A manual inverse fitting method adopted to obtain accurate cohesive models, sensitivity evaluation of comprehensively conducted. results show that G the experimental end‐notched flexure (ENF) nearly 20% greater than end‐loaded split (ELS). effect friction can be ignored, while all...
