Direct Tensile Test to Assess Healing in Asphalt [PDF]
Transportation Research Record: Journal of the Transportation Research Board, 2016 Asphalt concrete has the advantageous ability to heal. During rest periods, damage present in the material is restored to a certain extent. Healing of the material can be observed in its regaining of strength and stiffness after rest periods. In this paper, a new test method is presented.

CURRENT COGNITION OF ROCK TENSILE STRENGTH TESTING BY BRAZILIAN TEST [PDF]
Rudarsko-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 ...

Direct Tensile Test on Brittle Rocks with the Newly Developed Centering Apparatus [PDF]
Geotechnical Testing Journal, 2017 Abstract Failure of brittle rock normally initiates from tensile fracture due to its extraordinary lower resistance to tension rather than to compression. Intensive study on the deformability and accurate acquirement of the mechanical properties of rock under tensile stress is crucial for the stability analysis of rock slope and rock ...

Numerical Simulation of Tensile Failure of Concrete in Direct, Flexural, Double Punch Tensile and Ring Tests [PDF]
Periodica Polytechnica Civil Engineering, 2016 The present study considers the tensile strength of concrete samples in direct, flexural, double punch and ring tests using both of the experimental tests and numerical simulation (particle flow code 2D). It determined that which one of indirect tensile strength is close to direct tensile strength.
