ASTM D2936
Full Name
ASTM D2936 – Standard Test Method for Direct Tensile Strength of Intact Rock Core Specimens
Scope
ASTM D2936 is a standard test method used to determine the direct tensile strength of intact rock core specimens. This test is essential for evaluating the mechanical properties of rock materials, particularly for applications in civil engineering, mining, and geological engineering.
The test involves subjecting a cylindrical rock core specimen to a uniaxial tensile load until failure occurs. The tensile strength is calculated by dividing the maximum load applied by the cross-sectional area of the specimen. This test is commonly used to assess the rock’s resistance to tensile stresses, which are prevalent in structures such as bridges, dams, and tunnels.
Key factors influencing the test results include:
- Specimen preparation: the quality of the core specimen, including its size, orientation, and surface condition, can significantly affect the test results.
- Testing machine: the accuracy and sensitivity of the testing machine used to apply the tensile load are crucial for obtaining reliable results.
- Test environment: factors such as temperature, humidity, and loading rate can influence the tensile strength of the rock.
