Journal ArticleDOI
Apparent fracture toughness of Si3N4-based laminates with residual compressive or tensile stresses in surface layers
TL;DR: In this article, the effect of macroscopic residual stresses on the fracture resistance and stable/unstable crack growth in Si3N4/Si3n4-30 wt% TiN layered ceramics has been investigated.
Journal ArticleDOI
Crack arrest in Si3N4-based layered composites with residual stress
TL;DR: In this article, the effect of macroscopic residual stresses on fracture resistance and crack arrest in non-symmetric Si3N4/Si3n4/xTiN (x ¼ 20, 30 wt%) layered specimens was investigated.
Journal ArticleDOI
Mechanical properties and residual stresses in ZrB2–SiC spark plasma sintered ceramic composites
R. Stadelmann,Mykola Lugovy,Nina Orlovskaya,P. Mchaffey,M. Radovic,Vincenzo M. Sglavo,Salvatore Grasso,Michael J. Reece +7 more
TL;DR: In this paper, the distribution of thermal residual stresses and the effect of applied external load on their re-distribution were studied using micro-Raman spectroscopy, and their experimentally obtained values were compared with the piezospectroscopic coefficients both published in the literature and calculated theoretically.
Journal ArticleDOI
Robust design and manufacturing of ceramic laminates with controlled thermal residual stresses for enhanced toughness
Nina Orlovskaya,Mykola Lugovy,V. Subbotin,Oleksandr Radchenko,Jane W. Adams,Munjal Chheda,James Shih,Jag Sankar,Sergey Yarmolenko +8 more
TL;DR: In this paper, the authors developed boron carbide-silicon carbide layered ceramics with controlled compressive and tensile stresses in separate layers, which can provide high apparent fracture toughness and damage tolerance.
Journal ArticleDOI
