1. Effect of grinding and aging on subcritical crack growth of a Y-TZP ceramic
Abstract This study aimed to investigate slow crack growth (SCG) behavior of a zirconia ceramic after grinding and simulated aging with low-temperature degradation (LTD). Complementary analysis of hardness, surface topography, crystalline phase transformation, and roughness were also measured. Disc-shaped specimens (15 mm Ø × 1.2 mm thick, n = 42) of a ful

2. Tenacidade à fratura , crescimento subcrítico de trinca e limite de fadiga de compósitos resinosos experimentais com diferentes tamanhos de partículas de carga / Fracture toughness, subcritical crack growth and fatigue limit of experimental resin composites with different filler sizes.
O objetivo desta pesquisa foi verificar a influência de diferentes tamanhos de partículas de carga na tenacidade à fratura (KIc), nos parâmetros do crescimento subcrítico de trinca (n e f0) e de Weibull (m e 0), na longevidade estimada pelo diagrama tensão-probabilidade-tempo (SPT) e no limite de fadiga cíclica (LFC) de compósitos resinosos experimen

3. Fracture toughness measurements of LPS-SiC: a comparison of the indentation technique and the SEVNB method
Many methods are currently used to measure the fracture toughness of ceramic materials. Methods based on crack-length measurements of cracks introduced into the sample surface by the Vicker's indentor have the advantage that they are easy to use, but are very unreliable due to subcritical crack growth and the difficulty in determining the exact length of the
