Producing precision parts requires good control of the production parameters. When casting thermoset polymers an understanding of the curing process, with its heat release and associated temperature changes, is important. ...

Adhesion, friction and leakage in contacts with elastomers is central to many technologically demanding applications such as tires, seals, wiper blades and syringes to just name a few. These tribological systems are very ...

There is a growing interest in replacing steel tubes that operate in high pressure and high temperature environments with composite tubes. Such applications can include drilling risers and drill strings for the offshore ...

High performance composite parts require strict tolerances in all directions before the parts are ready to be used. Numerous of machining and assembly operations are often required to obtain the desired geometry and ...

En Digital Tvilling (Digital Twin) ble utviklet for å kalkulere skade fra kryp og utmatting på grunn av en-akset belastning i plastkomponenter. Den Digitale Tvillingen gjorde en kvantitativ analyse av skaden som oppstår ...

Glass fibers and fiber-reinforced composites degrade when exposed to water. Understanding the dissolution behaviour of glass in fiber-reinforced composites is necessary to predict the changes in physical and mechanical ...

Filament wound composite pressure vessels have found use throughout many industries for storing high-pressure gases. The ability to investigate the vessels for possible damage from accidental impact loads is important for ...

Icing of operating structures in the Arctic areas causes difficulties for ships and offshore drilling units. The large amount of accreted ice on these structures can make the ship turn over, and makes the work both challenging ...

The objective of this thesis is to explore how a new type of buoyancy material foroshore applications will perform under operating conditions. This includes buoy-ancy loads and extreme hydrostatic pressure. The new material ...
