Horizontal Compression Test: A Proposed Method for Indirect Determination of Tensile Strength of Stiff Soils and Soft Rocks

open access: yesFrontiers in Earth Science, 2022
Tensile strength is an important parameter in many engineering applications. In loess slopes, for instance, it governs the development and propagation of tension cracks that usually ultimately lead to crack–sliding and toppling failures, which are among ...

Tensile Properties and Tensile Failure Criteria of Layered Rocks

open access: yesApplied Sciences, 2022
Rocks are less resistant to tension than to compression or shear. Tension cracks commonly initiate compression or shear failure. The mechanical behavior of layered rocks under compression has been studied extensively, whereas the tensile behavior still ...

Using four-point flexure test to investigate effects of temperature and bar size on the tensile properties of GFRP bars

open access: yesPolymer Testing, 2022
Glass fibre reinforced polymer (GFRP) bars have been increasingly used in structures due to their advantages However, the effect of temperature variation is likely to degrade their mechanical behavior. In this experimental study, the tensile strength and

Loading Rate Effect of Rock Material with the Direct Tensile and Three Brazilian Disc Tests

open access: yesAdvances 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 ...

Indirect Tensile Strength Test on Heterogeneous Rock Using Square Plate Sample with a Circular Hole [PDF]

open access: yesLithosphere
An 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

open access: yesDental 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]

open access: yesE3S 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.
