1) R-Curve behavior 阻力曲线行为1. Based on the theory of R-Curve behavior,the history and nowaday' s status of research on R-Curve behavior for engineering ceramics are reviewed. 本文简要说明了工程陶瓷材料裂纹扩展阻力曲线(R—Curve)行为的理论基础,阐述了陶瓷材料阻力曲线行为研究的历史和现状,...
Since then this favorable crack resistance (R-curve) behavior has gainedconsiderable interest in the ceramic community. The involved toughening mechanisms have been studiedand the recognized principles of energy dissipation and crack tip shielding /1-3/ are increasingly utilizedto tailor ceramics and ...
Such R-curve characteristics were discussed based on observation of the fracture surfaces with a scanning electron microscope and the corresponding crack propagation-path behavior.doi:10.1016/j.ijadhadh.2020.102762Yousuke Kouno aMakoto Imanaka b

Both materials exhibited rising R-curve behavior. The Si3N4-TiN composites, however, displayed better damage tolerance and higher resistance to crack growth. From TEM observation, it was inferred that this superior performance of Si3N4-TiN composites can be attributed mainly to stress-induced ...
To better understand the role of grain size and grain-boundary adhesion on the fatigue threshold R-curve behavior of grain bridging ceramics, a study was conducted on the fatigue threshold behavior of 99.5% pure polycrystalline alumina with two different microstructures (fine and coarse) and in ...
3. The crack-growth-resistance behavior or R-curve behavior of Al2O3/SiCw ceramic cuttingtool material was obtAlNed by employing the Vickers indentation/fracture stress technique. 结果表明,裂纹扩展量较小时,R曲线较陡;裂纹扩展量较大时,R曲线趋于平缓。

R-curve behavior is one of these mechanisms where increase of fracture resistance with the extension of crack occurs. In such cases, 2P-Weibull distribution may not be the best fitting distribution function based on the goodness-of-fitness tests. This article examines the effectiveness of three-...
