Tensile Strength and Fracture Surface Morphology of Granite Under Confined Direct Tension Test
Rock Mechanics and Rock Engineering, 2021The tensile strength of rock is a crucial parameter for the stability assessment and reinforcement design of rock engineering, which is commonly determined by indirect tension test or uniaxial direct tension test. However, the rock in slopes and underground caverns is often in a direct tension stress state under confining pressure, due to the stress ...

Development of a New Push–Pull Direct Tensile Strength Testing Apparatus (PPTA)
Geotechnical Testing Journal, 2014Abstract Since direct tensile testing is time-consuming and expensive, the Brazilian test may overestimate the tensile strength of rocks because of its biaxial stress instead of the uniaxial tension condition, an alternative testing method is required to determine tensile strength of intact rock samples.

The Suggestion of Testing Method for Analysis of Tensile Strength of Multi-Directional GFRP Plate
Journal of the Korea Concrete Institute, 2011In this study, a standardized test method to analyze tensile properties of multi-directional GFRP plate was proposed. Presently, tensile strength test of FRP composite reinforced with isotropic and orthotropic fiber is standardized according to ISO standard. Also, even though many studies were performed on test method to analyze the dynamic properties,

American Journal of Orthodontics and Dentofacial Orthopedics, 1994
The stress levels within the cement layer (hence, the apparent strength) of a direct bonded orthodontic bracket depends, to a large extent, on the alignment of the tensile loads that are applied to the specimen. The purpose of this analysis was to determine how the construction of a ligature wire harness affects the alignment of the applied loads ...

Comparison of tensile strength values of rocks determined by point load and direct tension tests
Rock Mechanics and Rock Engineering, 1997A number of methods exists to fail rock in tension. In general the experimental results obtained by these methods differ, and it is not known how to quantitavely compare them other than by empiricism, even to obtain a value for tensile strength. Thus at present, these simple and very useful tests which measures strength indirectly have their values ...

Direct Tensile Strength Testing at 6 Hours of Fiber Reinforced Concrete Mortar Fractions
SP-155: Testing of Fiber Reinforced Concrete, 1995The prime consideration in minimizing concrete cracks in the field is to maximize the early (6-hour) tensile strength development to resist the volume reduction due to rapid water loss. This paper describes a test method, which simulates field conditions, for measuring direct tensile strength soon after initial set at 6 hours.
