Ceramic composites reinforced with nanoscale materials such as nanotubes are widely expected to have superior mechanical properties compared with more conventional composite materials. However, new work shows that the toughness of these nanocomposites can ...
Axial tension-tension fatigue experiments were performed on pultruded glass fiber reinforced polymer (GFRP) plates in a laboratory environment. Different full-scale specimen shapes were examined: plate strips as-delivered, plate strips with tabs and plates ...
Three-dimensional numerical simulations are performed to investigate the dynamic tensile properties of ceramics, using explicit dynamic FEM and cohesive element techniques. A micro-cracking model considering the stochastic distribution of internal defects ...
Owing to its porous cellular structure and polymeric components, wood can be easily shaped in its transversal direction when it is heated and has sufficient water content. Thanks to this thermohydrous behaviour many manufacturing processes such as densific ...
Recently, high-strength zirconia-toughened alumina (ZTA) ceramic substrates have attracted interest, because they offer much improved mechanical properties over straight alumina, while maintaining advantages such as good thermal conductivity and chemical s ...
This paper describes new polymer/ceramic photosensitive resins that can be used in the microstereolithography process for manufacturing complex 3D components in composite material. These new resins contain high loads (up to 80 wt.%) of alumina nanoparticle ...
Force and pressure sensors based on the piezoresistive properties of thick- film resistors have recently found wide application due to their low cost, reliability, and relatively good precision. Achieving high elastic mechanical strains is important to max ...
A Green's function method (GFM) for simulating fiber damage evolution and tensile strength in fiber-reinforced composites is compared in detail to the predictions of the standard shear-lag model (SLM) widely used in the literature. The GFM extracts the in- ...
The mechanisms of deformation and failure in Al-Si nanocomposites, formed by adding Si particles to Al nanocrystalline materials, are investigated using molecular dynamics. The deformation and fracture mechanisms are found to be different in the Al-Si comp ...
