摘要

实验研究了硅化石墨 SG-P0.5 制成的圆柱形样品，应变速率范围很广（10-4 至 103 1/s）。在保留碎片的条件下进行准静态和动态加载。施加准静态压缩并现场记录声发射信号。数据处理和碎裂统计数据的分析表明，硅化石墨在加载条件下发生了破坏。

Dynamic Fragmentation of Ceramics Based on Carbon and Silicon Carbide

Cylindrical samples made of siliconized graphite SG-P0.5 are experimentally studied in a wide range of strain rates (10^-4 to 10³ 1/s). Quasi-static and dynamic loading is performed under conditions of fragment preservation. Quasi-static compression is applied and acoustic emission signals are recorded in situ. The data processing and the analysis of the fragmentation statistics show the destruction of siliconized graphite under the loading conditions.
