The structural integrity and reliability of glass components are key issues for concentrated solar power (CSP) systems. For example, the glass windows in a solar furnace may suffer catastrophic fracture due to thermal and structural loadings, inclu

Due to the importance of glass components in Concentrated Solar Power (CSP) systems, an integrated assessment procedure conceived to facilitate the design of an intrinsically brittle component, limiting the amount of calculations, is presented. Since

Flowing gaseous ammonia NH3 with suppressed extent of dissociation (un-cracked NH3) is acknowledged to function as a powerful nitriding medium to realize formation of metal nitride MNx with considerably high N/M ratio x that cannot be achieved throug

In petreous materials, the mechanisms causing wear are several depending on which system we need to focus in. This work describes how it is possible to employ the lateral crack system, initially outlined to explain the wear of ceramic materials, to u

This paper describes the advantages and disadvantages of using different methodologies that apply bending fixtures for determining the fracture toughness of different stones. In general, the experimental results tend to show less variability when app

The sintering process of diamond–metal matrix hot-pressed tools, usually used for cutting hard materials (e.g., stone cutting) originates residual stresses, which should be taken into account in the performance of the tool. The work concerns the us

This paper describes and discusses the adequacy of Weibull statistical analysis to analyse the bending strength of granite. The experimental results show that strength variability is related with a specific origin of failure. This conclusion is based

The failure of carbon fibre bundles of Tenax 5131 HTA with 6000 filaments is characterised using the European Standard EN 1007-5. It is shown that the addition of liquid paraffin to the bundle causes a global change of the load-displacement curve and

Fracture-stress data and fractographic examination for the identification of the fracture origin are presented for two types of brittle materials (tungsten carbide and silicon carbide (SiC)) tested either in three- or four-point bending. The results

Two dynamic test methodologies, the resonance method and the ultrasonic method, are used for assessing the elastic behaviour of granitic rocks. The experimental results obtained using two types of specimens: (i) rectangular beams (parallelepiped spec
