Loading-Rate Dependency of Uniaxial and Indirect Tensile Strength.

open access: yesShigen-to-Sozai, 1993
Uniaxial and indirect tensile strength of Sanjome andesite was obtained under air-dried and water-saturated conditions. It was found that the strength increases with loading rate in both conditions.The difference in loading-rate dependency can not be observed between uniaxial and indirect tensile tests. And also the amount of strength increase with ten

Stress analysis of asphalt mixture in the indirect tensile strength test

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract Nowadays asphalt mixture is the most used material in the construction and reconstruction of roads. It is used for its advantages, such as availability of materials, flexibility and no need for dilatation. However, the asphalt mixture has one disadvantage, namely temperature sensitivity.
