Strength analysis of engineering high temperature resistant ceramic materials

High temperature resistant ceramic materials can be divided into structural ceramics and functional ceramics.The mechanical properties of materials mainly study the elastic or plastic deformation of materials under the action of external forces, the ability of materials to resist deformation and the laws of failure or destruction of materials.Ceramic materials are often bound by ionic bonds, covalent bonds, or a mixture of the two.Below the strength analysis of engineering ceramic materials, I hope you can understand.

From the characteristics of the structure, this kind of crystal rigidity is strong, the material on the whole is mainly high hardness, wear resistance, high temperature resistance and corrosion resistance, but brittleness, poor plasticity, not easy to process, thermal shock resistance is poor, strength dispersion.When such materials are loaded, cracks in the interior or surface will easily expand and cause stress concentration, causing sudden catastrophic fracture of the materials.

Strength is a material's ability to resist deformation and damage.According to the different loading forms, the stress inside the material can be classified into three types: tensile normal stress, compression normal stress and shear stress.Under the action of these stresses, the failure strength of materials can be divided into tensile strength, compression strength and shear strength.In addition, according to the characteristics of applied load, it is divided into bending strength, twisting strength, impact strength and fatigue strength.Above is the engineering wear-resistant ceramic material strength analysis, I hope you can firmly grasp.
