background: casein phosphopeptide-amorphous calcium phosphate (cpp-acp) is applied for remineralization of early caries lesions or tooth sensitivity conditions and may affect subsequent resin bonding. this in vitro study investigated the effect of cpp-acp on the shear bond strength of dental adhesives to enamel. materials and methods: sixty extracted human molar teeth were selected and randomly...

background: dental surfaces prepared with different er:yag laser distance may have different characteristics compared with those prepared with conventional instruments. the aim of this study was to investigate the effect of er:yag laser irradiation distance from enamel and dentin surfaces on the shear bond strength of composite with self-etch and etch and rinse bonding systems compared with con...

Abstract The evaluation of shear stress versus displacement curves is in the main focus geotechnical engineering. Such curves, depending on rock assessed, consist a quasi-linear section, followed by “kick” representing peak strength, and residual part, mostly parallel to abscissa. aim present study facilitate future automatic detection these crucial characteristics take step towards replacing t...

This paper investigates the shear strength of municipal solid waste (MSW) using the back analysis of failed waste slopes as well as field and laboratory test results. Shear strength of MSW is a function of many factors such as waste type, composition, compaction, daily cover, moisture conditions, age, decomposition, overburden pressure, etc. These factors together with non-standardized sampling...

The purpose of this research was to determine the shear strength of a unidirectional carbon-®bre/epoxy composite by means of the 10 o€-axis and 0 Iosipescu specimens subjected to shear. Detailed non-linear ®nite-element computations of these two tests were conducted, taking into account the actual non-linear material behavior of the composite. The tests were compared in terms of stresses and st...

verifying the behavior of shear walls in a tall building requires reliable response results. this paper examined nonlinear fiber element modeling of a slender reinforced concrete shear wall during large-scale shaking table testing. the goal was to understand and validate the inelastic responses given by fiber models using time history analysis. reasonable agreement was found between the numeric...
