Archivio Istituzionale della RicercaA torsion test on hour-glass-shaped samples with a full joined or a ring-shaped joined area was chosen to measure shear strength of glass–ceramic joined silicon carbide. Shear strength of about 100 MPa was measured for full joined SiC with fracture completely inside their joined area. Attempts to obtain this shear strength with a ring-shaped joined area failed due to mixed mode fractures. On the contrary, full joined and ring-shaped steel hour-glasses joined by a glass–ceramic gave the same shear strength, thus suggesting that this test measures shear strength of joined components only when their fracture is completely inside their joined area.

Abstract
A torsion test on hour-glass-shaped samples with a full joined or a ring-shaped joined area was chosen to measure shear strength of glass–ceramic joined silicon carbide. Shear strength of about 100 MPa was measured for full joined SiC with fracture completely inside their joined area. Attempts to obtain this shear strength with a ring-shaped joined area failed due to mixed mode fractures. On the contrary, full joined and ring-shaped steel hour-glasses joined by a glass–ceramic gave the same shear strength, thus suggesting that this test measures shear strength of joined components only when their fracture is completely inside their joined area.
