“…This adhesive was chosen such that its elastic properties are close to those of the bulk polymer. Thereby, the interface can be modeled as a line without any thickness but with different bonding strengths and fracture toughnesses (Xu et al 2004b). Material properties of the various combinations of bonded interfaces are provided in Krishnan and Xu (2011a).…”

In this paper, interface crack initiation at V-notches along adhesive in bonded Polycarbonate (PC) and Poly Methyl Methacrylate (PMMA) subjected to mixed-mode loading conditions was investigated based on a combined experimental, finite element and matched asymptotic analysis. The V-notch specimens with an adhesive interface starting from its tip made at different notch angles were tested under threepoint bending conditions. The experimental observations show that the specimens mainly fail by cracks along the interface. Also, the load at the crack initiation increases when the notch angle increases. The computational results are then used to explain and to correlate with the experimental data. A two-fold criterion developed by Leguillon (Eur J Mech A/Solids 21:61-72 2002) that requires a simultaneous satisfaction of both Griffith energy and stress conditions for the crack initiation at a notch in the specimen made of a homogeneous brittle material is first extended for

“…The objective of this study is to analyze the effect of the interfacial stress distribution on the strength measurements. In order to avoid complicated failure modes during shear tests [17], and to only focus on the shear failure of an interface, we design and test bonded polymers and metals such that the bonded interface is the only weak path leading to the final shear failure.…”

An integrated experimental and numerical analysis is carried out to study the interfacial shear strength of bonded materials. Two types of shear tests, namely the Iosipescu shear test, and the short-beam shear test are employed to understand the effect of interfacial stress on the interfacial shear strength measurements. The measured average shear strengths are very close, even though the interfacial shear stress distributions of these two kinds of specimens are very different. Therefore, we conclude that the interfacial stress distribution has the least effect on the interfacial strength measurement if the interfacial shear stress is non-singular.

“…[1,2] A number of attempts have been made to overcome the problems, which include the copolymerization of various acrylic monomers, however, causing another problems such as lower peel strength and harder handling. [3,4] Therefore, there is a strong need to develop durable nanocomposite adhesives keeping good adhesiveness. Although considerable efforts have been made in developing nanocomposites of acrylic monomer with inorganic nanoparticle, [5] nanocomposites also have low mechanical properties due to difference of surface energy between organic resin and inorganic nanoparticles leading to the separation of organic and inorganic part.…”

Surface-modified colloidal silica (M-CS) nanoparticles were successfully synthesized from colloidal silica (CS) and methyltrimethoxysilane using sol-gel method and characterized by Fourier transform-infrared spectroscopy. Both CS and M-CS were then incorporated into acrylic adhesives. M-CS particles in 2-ethoxyethanol had similar particle size to pure CS based on the characterization by DLS. The morphologies of M-CS particles in acrylic adhesives examined by TEM showed more homogeneous dispersities than that of pure CS which were aggregated and phase separated in acrylic adhesives. In addition, the thermal properties of the nanocomposite acrylic adhesives determined by thermogravimetric analyses and differential scanning calorimetry showed higher glass transition temperature and thermal properties than pure acrylic adhesives. Finally, the 180°peel strength of nanocomposite acrylic adhesives was higher than pure adhesives with improved durabilities.
