Abstract

The present paper describes a four-point bending fixture which has been designed for testing ceramic materials and the experimental procedures developed to obtain full-field representation of the out-of-plane displacements on the specimen surface under traction. The testing procedure, which can be extended to three-point bending tests, enables the errors due to a possible misalignment of the applied load to be detected and eliminated. The possibility of determining the elastic constants of the material from the displacements measured is also discussed.
