Abstract

The split Hopkinson pressure bar (SHPB) system and a universal testing machine were used to measure the fracture toughness of zirconia (ZrO₂) and alumina (Al₂O₃) ceramics across a wide range of loading rates from 1.0 × 10^-8 to 2.0 TPa·m^1/2·s^-1. The experimental-numerical method was used to determine the dynamic fracture toughness of the materials. The results exhibit a positive relationship between fracture toughness and loading rate as well as a negative correlation between fracture initiation time and loading rate for both of the ceramics. The analysis of fracture morphology reveals different micromechanism in the failure of the materials under different loading rates. This analysis offers an explanation for the dependency of fracture toughness on loading rates. Additionally, the incubation time criterion and its modified version were employed to describe the effects of loading rate on fracture toughness and fracture initiation time.

氧化铝和氧化锆陶瓷在大加载速率下的断裂韧性及破坏机理

采用分离式霍普金森压杆（SHPB）系统和万能试验机对氧化锆（ZrO2）和氧化铝（Al2O3）陶瓷在1.0 × 10-8 ~ 2.0 TPa·m1/2·s-1加载速率下的断裂韧性进行了测试。采用实验-数值方法测定了材料的动态断裂韧性。结果表明，两种陶瓷的断裂韧性与加载速率呈正相关，而断裂起始时间与加载速率呈负相关。断裂形貌分析揭示了不同加载速率下材料破坏的微观机制不同。这一分析为断裂韧性对加载速率的依赖性提供了解释。此外，采用孵育时间准则及其修正版本来描述加载速率对断裂韧性和断裂起裂时间的影响。

期刊介绍： The International Journal of Impact Engineering, established in 1983 publishes original research findings related to the response of structures, components and materials subjected to impact, blast and high-rate loading. Areas relevant to the journal encompass the following general topics and those associated with them: -Behaviour and failure of structures and materials under impact and blast loading -Systems for protection and absorption of impact and blast loading -Terminal ballistics -Dynamic behaviour and failure of materials including plasticity and fracture -Stress waves -Structural crashworthiness -High-rate mechanical and forming processes -Impact, blast and high-rate loading/measurement techniques and their applications
