On the In-Plane Shear Response of the High Bond Strength Concrete Masonry Walls [PDF]
Materials and Structures/Materiaux Et Constructions, 2017 Conventional unreinforced masonry walls subject to in-plane shear loading fail due to exceedance of shear and tensile bond strengths. This paper examines whether or not the in-plane shear capacity of masonry walls would increase with the increase in the ...

Shear bond strength and microleakage of dentin bonding systems
The Journal of Prosthetic Dentistry, 1991This study evaluated the shear bond strength and microleakage of class V non-retentive restorations with 10 different dentin bonding systems. Some were tested with different composite resins. For the shear bond test, eight specimens were prepared for each product and tested in a universal testing machine. For the microleakage test, 158 V-shaped class V

Shear bond strength of four orthodontic bonding systems
American Journal of Orthodontics and Dentofacial Orthopedics, 1990Recently new orthodontic bonding systems have been developed for attachment of brackets to the etched facial surfaces of teeth. Two of these new systems use bonding agents that contain solvents. It is claimed that this improves the polymerization of the unfilled resin primer and may increase bond strength.

Shear bond strength and microleakage of All-Bond.
American journal of dentistry, 1994The shear bond strengths (SBS) were determined to enamel etched with Uni-Etch (Procedure A) or treated with the mixed Primer A and B (Procedure B), to dentin treated with the Dentin Conditioner (Procedure C) or etched with All-Etch (Procedure D), to amalgam treated with the mixed Dual Opaquer Base and Catalyst which was allowed to self cure (Procedure ...

The shear strength of enamel — composite bonds
Journal of Dentistry, 1977Abstract The shear bond strengths of several commercial materials to etched enamel were evaluated using a modified punch test. An overall significant difference between the bond strength values for the composites was established. Increasing the punch speed was observed to have a detrimental effect on shear bond strength, and investigations into ...

Shear Strength of the Composite Bond to Etched Porcelain
Journal of Dental Research, 1987The shear bond strength of composite resin to porcelain was investigated to optimize variables for bonding porcelain laminate veneers. Scanning electron microscopy was initially used to examine the surface configuration of porcelain prepared under various conditions.

Shear bond strength in porcelain-metal restorations
The Journal of Prosthetic Dentistry, 19801. The push test method showed higher shear bond strength values than the pull test method. 2. A bond strength of 4,500 to 6,000 psi between the dental stone and metal rod was eliminated in a waxed-rod test. Although the strength values were lower in waxed-rod tests, they were believed to be true shear bond strength values. 3.

Dentin shear bond strength of compomers and composites
Dental Materials, 2000The aim of this study was to compare the shear bond strengths and fracture characteristics of two compomers bonded with a single step bonding agent with two modern composites, a microfil and hybrid, bonded with a fourth generation bonding agent.Freshly extracted human third molars were sectioned parallel to the occlusal surface to expose midcoronal ...

Comparison of in vivo and in vitro shear bond strength
American Journal of Orthodontics and Dentofacial Orthopedics, 2003Much of the research into composite adhesives suggests that these materials will deteriorate in the oral environment, but most of these claims are made on the basis of extrapolation from in vitro experiments; relatively little in vivo research has been conducted into the mechanical properties of composite adhesives.

Shear bond strengths of orthodontic plastic brackets
American Journal of Orthodontics and Dentofacial Orthopedics, 2000The purpose of the present study was to evaluate the shear bond strengths of plastic brackets and the influences of the bracket filler contents on the bonding. The shear bond strengths of 4 plastic brackets (Spirit; Spirit MB; Clear Bracket; Aesthetic-Line) bonded to enamel with 4 orthodontic adhesives (Orthomite Superbond; System 1+; Transbond XT; and
