摘要
叙述细观力学的主要研究方法、模型及其应用 ,并针对陶瓷材料的细观结构 ,论述提高陶瓷材料韧性的方法 ,如相变增韧、微裂纹增韧。
Micromechanics is a research technique of studying mechanical properties of materials. It's studying scales is between continuum mechanics and micro mechanics. Alumina ceramics is good advanced ceramics widely used at the present time, which have many merits, such as high hardness, good wear-resisting property and good corrosion, but its toughness is bad .The main studying method, model and application of micromechanics has been discussed, the method of increasing ceramics' toughness has been discussed against the ceramics' microstructure too, such as phase transformation toughening, microcrack toughening, fiber or whisker toughening.
