Fracture toughness of ceramics and ceramic composites

Fracture Resistance of Ceramics: Edge Fracture Method

“…With an improvement in the characteristics of ceramics and a continuous growth in production volumes of ceramic items, fracture resistance of these materials attracts the particular attention [2,3]. In this connection, corresponding national [4], European [5], and international standards [6 ] are developed as well as comparative evaluation of methods for studying their fracture resistance (Round Robins organized by ESIS, VAMAS, and Japan Society of Fine Ceramics [2 ]) is performed with the participation of leading specialists of the world.…”

Deformation and Damage Accumulation in a Ceramic Composite under Dynamic Loading

“…To evaluate σ tension , the data from [2,3] were used. The present work uses media damage parameter D considered as a result of accumulation of damage increments during the microstructure evolution at lower scale level over the time from t 0 to t 0 + m Δt [4][5][6][7]: (2) Where is the increment of the damage parameter over the deformation time Δt, is the intensity of inelastic deformation, is the ultimate strain at the moment of macroscopic fracture.…”

Effect of Polymer Wrapping on the Properties of ABS/MWNT Nanocomposites

“…, 나노 크기의 구형 또는 판상 구조의 적층 형태를 지닌 세라믹 성분 3,4) , 그리고 † [6][7][8][9][10] , 플라즈마처리 11,12) , UV-오존처리 13,14) 등으로 CNT 표면에 극성기를 도입 하는 방법이 가장 널리 이용되고 있다. …”
