A commercially available polycrystalline alumina is tested u

A commercially available polycrystalline alumina is tested using 3 different methods: 3-point bend, 4-point bend, and uniaxial tension. The resulting MOR values are 550, 410, and 175 MPa, respectively. What conclusions can you make about the material from these data?

Solution

It can be seen that modulaus of resilience is low in uniaxial tension test. therefore it can be concluded that the material can not withstand the shocks or shock load within elastic limit.
