“…. Note the poor agreement between results for the three indentation equations evaluated (Anstis et al, 1981;Niihara, 1983;Miyoshi, 1985), while only in one case did the indentation toughness match the actual toughness. Similar results have been reported in many studies on many different ceramic materials, along with both increasing and decreasing apparent toughness with increasing indentation load (Li et al, 1989;Ponton and Rawlings, 1989b;Ghosh et al, 1996;Quinn and Bradt, 2007).…”

“…Ponton과 Rawing (8,9) 은 다양한 압입 파괴인성 평가식에 대해 조사했으며, 대부분의 평가식으로 얻은 파괴인성과 실 파괴인성의 오차가 약 30 % 이상임을 보였다. 아울러 Quin과 Bradt (10) 도 대표적인 압입파괴인성 평가수식 (2,11,12) 으로 예측된 파괴인성과 실 파괴인성 비교해 Vickers 압입시험의 한계성을 지적했다. 이에 다양한 형태의 유한요소해석 및 측정기술을 활용해 재료특성에 따른 압입 파괴인성평가 연구가 시도되고 있다.…”
