Loading Rate Effect of Rock Material with the Direct Tensile and Three Brazilian Disc Tests
Advances in Civil Engineering, 2019 A series of experimental tests were conducted to investigate the effects of loading rate on the tensile strength of sandstone by using four test methods, including a direct tensile method and three typical Brazilian disc methods (plate loading, circular ...

IOP Conference Series: Earth and Environmental Science, 2019 In this study, the determination of the direct and indirect tensile strength of granite rock was carried out in compliance with related standard test methods. In order to analyze rock tensile strength between direct (with using a new dumbbell shape) and indirect (Brazilian tensile strength) test methods were conducted and obtained results were compared

Indirect Tensile Strength Test on Heterogeneous Rock Using Square Plate Sample with a Circular Hole [PDF]
LithosphereAn indirect testing method for determining the tensile strength of rock-like heterogeneous materials is proposed. The realistic failure process analysis method, which can consider material inhomogeneity, is applied to model the failure process of the ...

Tensile and shear bond strengths of orthodontic direct-bonding adhesives
Dental Materials, 1988 Abstract Bond strength and durability of 6 direct-bonding orthodontic cements, including 2 newly developed materials, one a 4-META/MMA resin and the other a chemically and lightcured microfilled resin, were investigated in vitro . The necessity of a sealant resin was also examined. The facial surfaces of extracted bovine teeth were ground on silicon-

Tensile strength of a vegetated and partially saturated soil [PDF]
E3S Web of Conferences, 2020 Vegetated soil’s shear strength has been usually assessed through direct shear tests and under triaxial compression stress paths while less is known about its behaviour under tensile stress.

Numerical study on tensile failures of heterogeneous rocks
Journal of Rock Mechanics and Geotechnical Engineering, 2020 Many experimental results have demonstrated the apparent discrepancy of a rock material between its flexural tensile strength measured using various bending methods and its tensile strength measured using direct tension method or Brazil disc (BD) method.

Mechanical Characterization of Cemented Paste Backfill
Eng, 2023 Mechanical characterization is important to the design and analysis of cemented paste backfill (CPB) structures. Unconfined compressive strength (UCS) tests have been widely used owing to their relative simplicity to characterize a material’s response to

Effect of Aspect Ratio in Direct Tensile Strength of Concrete [PDF]
Journal of the Korea Concrete Institute, 2003 Although concrete members are not normally designed to resist direct tension, the knowledge of tensile strength is of value in estimating the cracking load. In general, there are three types of test method for tensile strength ; direct tension test, flexural tension test, and splitting tension test.
