Verification of the Double-Torsion Equation by Using Different Thickness Samples of a Machinable Glass-Ceramic

The double‐torsion technique is commonly used to measure fracture toughness. A finite thickness of samples is used for the measurement; however, for samples of varying thickness, a correction factor is introduced in the double‐torsion equation. This was verified by using machinable glass ceramic sam...

Description
Summary:The double‐torsion technique is commonly used to measure fracture toughness. A finite thickness of samples is used for the measurement; however, for samples of varying thickness, a correction factor is introduced in the double‐torsion equation. This was verified by using machinable glass ceramic samples differing in thickness.
