A three-point bend test is performed on a block of ZrO2 that is 203.2 mm long,...
[10 marks] Question 2: A cylindrical specimen of a ceramic material is loaded using the three-point bending mode. Calculate () the minimum possible radius (in mm) of the specimen without fracture; (ii) the flexural modulus where the deflection of the sample is 0.45 mm, assuming that no plastic deformation occurs. Given that the applied load is 460 N, the flexural strength is 113 MPa, and the separation between load points is 50 mm. a) If cupric oxide (CuO) is exposed...
