This work aims to characterize the water uptake mechanisms of a two-component epoxy adhesive joint immersed in deionized water. The pore-type defects bulk after cure cycle are highlighted and characterized using X-ray µ-tomography. Two population patterns generated analyzed, for two different thicknesses. waterfront is not detectable by µ-tomography this because densities remain relatively close each other. Instead, volume variation kinetics pore filling have been accurately identified....
To investigate the mode I fracture properties of adhesively bonded joints after water ageing, authors reduced here width Tapered Double Cantilever Beam (TDCB) specimens to 5 mm (compared typical values encountered in literature at 10 mm). This was decided order reach desired absorption levels within a reasonable time. However, this operation found increase impact edge effects on results, which were illustrated by finite element simulations. Hence, improve consistency and stability crack...
The capabilities of structural bonding are more and used. Estimating the abilities an adhesive to endure repetitive loadings keep stable its mechanical properties along service life is essential point analyze in order conduct fatigue assessments. aim this study develop a predictive tool for describing behavior assembly under cyclic loadings. approach developed analyzes influence viscosity on based monotonic creep test results. Thanks evaluation viscous phenomena, it possible predict response...
To perform an evaluation of the abilities a bonded structure to endure repetitive loadings, characterizations structural adhesive joints mechanical behavior are key objectives. The aim this study is describe phenomena occurring in joint until appearance macroscopic crack. Using lap-shear type specimens, associated with stress concentrations, crack initiation generally appears early at edge joint, which makes it difficult identify phase. characterize more properly phase, designed limit...
Abstract In the present study, crack propagation behavior under cyclic loading of an epoxy‐based adhesive was investigated by means Arcan device, in mixed‐mode plane I+II. The strain energy release rate (SERR) calculated through inverse identification method using a Finite Element (FE) modeling. evolution cracked surfaces revealed three main stages during tests. It found that fatigue loading, propagated at value SERR per cycle lower than values critical monotonic loads. evolutions against...
