A New Flattened Cylinder Specimen for Direct Tensile Test of Rock

Sensors, 2021
In recent decades, researchers have paid more attention to the indirect tensile test than to the direct tensile test (DTT) of rocks, mainly due to difficulties in the alignment and the stress concentration at the end of an intact cylindrical specimen. In

Comparison of Test Methods for Determining the Tensile Strength of Soil and Weak Rocks

Frontiers in Earth Science, 2022
Tensile strength is a key parameter governing tensile cracking and subsequent failure of soil or rock mass. Existing methods for measuring tensile strength are mainly designed for hard materials and come with inherent problems.
