BACKGROUND Different in-vitro studies have reported various results regarding shear bond strength (SBS) of orthodontic brackets when SEP technique is compared to conventional system. This in-vivo study was designed to compare the effect of conventional acid-etching and self-etching primer adhesive (SEP) systems on SBS and debonding characteristics of metal and ceramic orthodontic brackets. MA...

• Debonding of solidified splat was observed under various impact conditions. Scraping test conducted to evaluate the adhesion strength splat. explains debonding behavior Tensile residual stress reduces scraping force and prevents removal splats is a crucial issue for thermal sprayed coatings, which greatly influences performance lifetime industrial components. The purpose this study provide an...

Abstract In this work, the effect of common functional groups, namely hydroxyl, formyl, carboxyl, and amine groups on interfacial behavior surface-modified glass fiber-reinforced epoxy is investigated at molecular scale. The properties epoxy/silica coated with different group systems are quantified by performing pulling test using steered dynamics simulations. It found that system hydroxyl has ...

We show how we can exploit our recently proposed algorithms for the solution of contact problem of elasticity to the 2D analysis of the interfacial debonding of samples that consist of several fibres embedded in a homogeneous matrix, aligned in the longitudal direction. The performance of the algorithm is demonstrated on analysis of deformations of samples of the fibrous composite material.
