An estimate of quartz content and particle size in porcelain tiles from young's modulus measurements
Dal Bó, Marcelo; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique; Gilabert Villegas, Francisco A.; Boschi, Anselmo O.; Hotza, Dachamir Elsevier (2017)The influence of quartz particle size, weight content and firing temperature on the Young's modulus of porcelain tiles was studied. To simulate a porcelain tile microstructure, an albite glass matrix with added crystalline ... -
Fracture patterns of quartz particles in glass feldspar matrix
Gilabert Villegas, Francisco A.; Dal Bó, Marcelo; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique Elsevier (2012)We report a comparison between experimental evidences and simulation results of the micro cracking in ceramic materials provoked by the cooling process. The solid model and the fracture process are carried out using the ... -
Fracture toughness and temperature dependence of Young's modulus of a sintered albite glass
Dal Bó, Marcelo; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique; Hotza, Dachamir; Gilabert Villegas, Francisco A. Elsevier (2013-03)Albite glass is an important component in many ceramic compositions, often used as liquid phase during the sintering process. Nevertheless, in spite of its almost ubiquous presence in the final microstructure of these ... -
Influence of beta-to-alpha quartz transition on residual stresses of a feldspar glass matrix composite: A relationship with catastrophic fracture due to thermal shock
Dal Bó, Marcelo; Gilabert Villegas, Francisco Antonio; Ortega Boschi, Anselmo; Sánchez-Vilches, Enrique; Cantavella, Vicent; Hotza, Dachamir Elsevier (2023-04-14)A wide range of porcelain-based materials is composed of quartz crystalline particles dispersed in a homogeneous glassy phase. During the cooling stage these composites are subjected to stresses related to the transition ... -
Modeling microstructural damage of silicate-based ceramics and its influence on macroscopic fracture strength
Gilabert Villegas, Francisco A.; Cantavella Soler, Vicente; Dal Bó, Marcelo; Sánchez-Vilches, Enrique Elsevier (2014-05-15)The aim of this work is to clarify the influence of quartz inclusions added to a vitreous matrix on the macroscopic fracture toughness (KICKIC). We use numerical simulations to model a silicate-based ceramic material as a ... -
Modelización mecánica del enfriamiento rápido en sistemas tipo gres porcelánico
Dal Bó, Marcelo; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique; Hotza, Dachamir; Boschi, A. O. Sociedad Española de Cerámica y Vidrio (2012-03)This paper analyses the effect of cooling on mechanical behaviour, in particular, on the residual stresses that appear when materials of the porcelain tile type are involved. However, these compositions have a very complex ...
