陶瓷和玻璃等无机非金属材料在我国国民经济建设中发挥着越来越重要的作用。由于它们的本征脆性和“宁碎不屈”的特性,这类材料也最容易发生突发性灾难事故、成为最不安全的材料。脆性材料的断裂、失效、疲劳破坏、腐蚀等问题均会引发一系列危及国民安全的灾难性事故。由于材料和构件的质量及损伤所引发的事故频发,给社会经济和人民财产安全带来了巨大的 Inorganic non-metallic materials, such as ceramics and glass, play an increasingly important role in the national economy of our country. Due to their intrinsic fragility and the character of “subduction”, such materials are also most prone to sudden catastrophic accidents and become the most unsafe materials. The problems of brittle fracture, failure, fatigue damage, corrosion and so on will lead to a series of catastrophic accidents that threaten national security. Frequent accidents caused by the quality and damage of materials and components have brought tremendous social and economic benefits to people’s property
