1.
In this paper, the effects of water environment and cyclic loading on the KI-V characteristics were studied by the crack growth tests using double torsion (DT) method under static and cyclic loading in both environments of air and water for the bio-ceramics of glass ceramics, mica glass ceramics, alumina and zirconia.
采用破坏力学中的双扭矩实验法,研究了玻璃陶瓷、云母陶瓷、氧化铝陶瓷、氧化铝陶瓷材料分别在大气、水环境中的静负荷和循环负荷下的裂纹扩展特性,阐明了水环境和循环负荷对材料裂纹扩展特性（K1-V特性）的影响。
