CURRENT COGNITION OF ROCK TENSILE STRENGTH TESTING BY BRAZILIAN TEST

open access: yesRudarsko-geološko-naftni Zbornik, 2015
Tensile strength in rock mechanics is a characteristic more frequently determined in the indirect rather than direct way. This paper presents a historical review of the development of the indirect method called the Brazilian test, comprising the period ...

Aggregate effect on the concrete cone capacity of an undercut anchor under quasi-static tensile load [PDF]

open access: yes, 2018
In the last decades, fastening systems have become an essential part of the construction industry. Post-installed mechanical anchors are frequently used in concrete members to connect them with other load bearing structural members, or to attach ...

Numerical Simulation of the Effect of Loading Angle on Initial Cracks Position Point: Application to the Brazilian Test

open access: yesApplied Sciences, 2021
The Brazilian Test is the most used test to determine the indirect tensile strength for brittle materials like concrete. It has been observed that the success of the test depends on the cracks initiation point position and therefore the arch loading ...

Water saturation induced changer in the indirect (Brazilian) tensile strength and the failure mode of some igneous rock materials [PDF]

open access: yes, 2020
The present study concentrates on water induced strength reduction and variation of the failure mode in indirect (Brazilian) tension tests of several igneous rock materials under three moisture cases of oven-dry, air-dry and fully saturated states.
