통계적 파괴 확률에 의한 Sin/Hip 질화규소의 신뢰도 분석 = Reliability Analysis of Statistical Failure Probability in Sin/Hip Si3N4

다국어 초록 (Multilingual Abstract)

MOR test and concentric ring test were performed to evaluate the failure probability of sin/hip Si3N4 under uniaxial and biaxial stress state, respectively. Their failure probabilities were analized with KARA program based on Weibull PIA model and Batdorf model with 5 criteria, and they were compared with experiments. PIA model is in best accordance with experiments in higher fracture strength regions, especially for Pf 0.3. But in lower fracture strength region, none of the models predicts the failure probabilities appropriately.
