Assessment of Direct Tensile Strength Tests in Rock Through a Multi-laboratory Benchmark Experiment

Rock Mechanics and Rock Engineering
AbstractThis study aims to experimentally assess repeatability and reproducibility of direct tensile strength (DTS) tests with deformability measurements on two types of rocks: Blanco Mera granite (Spain) and Cotta sandstone (Germany). The tests were conducted in four rock mechanics laboratories located in different countries (Canada, Germany, Spain ...

Development of a New Push–Pull Direct Tensile Strength Testing Apparatus (PPTA)

Geotechnical Testing Journal, 2014
Abstract 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, 2011
In 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,

Comparison of tensile strength values of rocks determined by point load and direct tension tests

Rock Mechanics and Rock Engineering, 1997
A 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, 1995
The 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.
