Evaluation and Standard Testing Methods for Elastic Modulus, Bending Strength, and Fracture Toughness of Advanced Ceramics

The basic mechanical properties of advanced ceramics are crucial for the design, preparation, and safe application of ceramic components. Although there are various standards at home and abroad to specify the testing of these properties, young researchers and designers of ceramics often have some problems in terms of operation or sample preparation during the performance testing process. In order to facilitate accurate understanding and acquisition of the basic mechanical properties of advanced ceramics, the main testing principles and standard testing methods by bending for elastic modulus, bending strength, and fracture toughness of advanced ceramics were summarized in this paper. The most commonly used standard testing methods, as well as related sample requirements, testing devices, testing procedures, and calculation methods are discussed. It is helpful and for accurate characterization and evaluation of the mechanical properties of advanced ceramic materials.
