A bundle of many fibers with stochastically distributed breaking thresholds is considered as a model of composite materials. The fibers are assumed to share the load equally and to obey Hookean elasticity up to the breaking point. The bundle is slightly overloaded which leads to complete failure. We...

AMO-kurset Skole på byggeplass (SPB) er finansiert av Aetat og gjennomført av en større ( J entreprenørbedrift. Kurset går over 40 uker, gir fullverdig VK1 eksamen i betongfag, anlegg og bergverk eller tømrerfag, og gjennomføres i sin helhet på en byggeplass. SPB bygger på en pedagogisk modell der...

The dielectric properties of dual-layer PZT/ZrO2 thin films were measured at microwave frequencies in both a metal–insulator–metal (MIM) capacitor and a coplanar waveguide (CPW) up to 50 GHz. Both PZT and ZrO2 films were prepared by the chemical solution deposition method. The measured dielectric...

We have used micromachining methods taken from the MEMS industry to fabricate acoustic matching layers for high frequency transducers. The matching layers are made as silicon-polymer composites, with acoustic impedance determined by the ratio between the two materials. Two different fabrication...

The effect of the fluidization air flow rate and the transport air velocity on the solids mass flow rate and the pressure drop along the transport pipe was investigated in a vertical air-lift. The use of two different materials, glass (150 μm) and zirconium oxide (260 μm) particles (Geldart's B...

The offshore industry faces challenges with corrosion resistance in hydraulic cylinders used in marine environments. Thermal spray coating appears to be a promising technique for replacing electroplated coating in many applications, but the performance of thermal spray coatings in highly corrosive...
