Shear tests

State of the art: Four-point asymmetrical

bending test

• ASTM C 1469-00(2005)

Pros

• It is the only standard available to test the shear strength of joined ceramics and ceramic composites

Cons

• Notches are needed if the joint strength is high

• Shear stress (within the middle of the joint) is not uniform.

• Positioning of loading pins is difficult
