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 MP a 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.
