Summary of Test
ASTM B769 is a testing standard that covers the double- shear testing requirements of wrought and cast aluminum alloy products.
This method determines the shear stress required to fracture the specimen, that is, the shear strength. A universal testing machine that conforms to the requirements of Practices E4 should be used to conduct this test. The shearing edges of the double-shear test fixture should have holes with a radius of no more than 0.013 mm (0.0005 in). Prior to conducting ASTM B769, it is important to read the entire specification in the relevant ASTM publication.
Recommended Equipment
Testing Procedure
- Cut and prepare the cylindrical test specimens as described in the standard.
- Mount the specimen into the double-shear fixture with the appropriate specimen orientation and direction.
- Apply load at the crosshead speed as found in the testing standard.
- Continue test to specimen failure. Results will be calculated by MTESTQuattro.
