Values for the flexural strength measured with four-point bending will be significantly lower than with three-point bending., Compared with three-point bending test, this method is more suitable for strength evaluation of butt joint specimens. Exposing a large volume of material to the maximum stress will reduce the measured flexural strength because it increases the likelihood of having cracks reaching critical length at a given applied load. more complex integral stress distributions through the sampleĪpplication with different materials Ceramics Ĭeramics are usually very brittle, and their flexural strength depends on both their inherent toughness and the size and severity of flaws.possibility to use as-fabricated materials.The four-point flexural test provides values for the modulus of elasticity in bending E f = Depth or thickness of tested beam, (mm)Īdvantages of three-point and four-point bending tests over uniaxial tensile tests include:
