Test Background
Flexural strength refers to the maximum stress at which a specific elastic beam breaks when subjected to a bending load. The flexural strength of ceramics depends on its inherent ability to resist fracture and the characteristics of the ceramic itself. Since these factors cause discreteness in ceramic strength, sampling testing is required. The Fine Ceramics Flexural Strength Test determines the room temperature flexural strength of fine ceramics and fiber-reinforced or particle-reinforced ceramic composites.
Zhongke Testing and Reliability Experiment Center has the capabilities of environmental testing and reliability performance testing of various fine ceramics, and provides professional flexural strength testing services for fine ceramics.
Scope of tests
Fine ceramics can be divided into two categories: structural ceramics and functional ceramics.
Structural ceramics: high-temperature ceramics, high-strength ceramics, superhard ceramics, corrosion-resistant ceramics
Functional ceramics: electronic ceramics, superconducting ceramics, optical ceramics, bioceramics, magnetic ceramics, energy storage ceramics
Test method
A bending load is applied to a beam specimen of rectangular cross-section until the specimen breaks. The specimen material is assumed to be isotropic and linear elastic.
The flexural strength of the specimen can be calculated from the critical load at fracture, the dimensions of the fixture and specimen.
