“…The study of residual stresses has been a fundamental research field in the design of structures and materials of very diverse nature such as concrete [6], metals [7], glass [8] composites [9] and advanced ceramics [10], [11]. However, its application to the case of traditional ceramic products in general, and the manufacture of ceramic tiles in particular, has been very scarce so far [1], [12]. As mentioned above, the manufacturing requirements (fast firing cycles) and product demands (large formats) have led to the need to address, in a rigorous way, the problem of residual stresses of thermal origin during the manufacture of porcelain tiles.…”

“…In the works previously discussed on residual stresses in ceramic tiles, Cantavella et al [12] determined thermal stresses inside unglazed porcelain tiles by using the strain relaxation method, also known as the crack-compliance technique [13][14]. These authors showed that for two different commercial products, tiles presented similar stresses profile with compressive stresses at the tile surface.…”

“…Portanto, de 70 a 85% da diferença inicial é recuperada em uma retração diferente durante o processo de sinterização. Isto implica que qualquer diferença na densidade aparente a seco é compensada em termos de retração diferencial, que pode ser perigosa, e ser a causa provável de uma deformação permanente e de tensões residuais depois da queima [38][39][40].…”

“…Para garantir o alto desempenho técnico desses produtos, os mesmos devem apresentar porosidade bastante reduzida. Esta é alcançada através de queima em temperaturas relativamente altas para que uma elevada quantidade de fase líquida se forme e preencha os poros existentes no compacto verde [1]. Como consequência, intensifica-se a tendência à deformação piroplástica para essa tipologia de produto.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
