Abstract:

Metal cutting is one of the most commonly occurring manufacturing processes in the industry and major effort is made to improve its processes. Cutting tools are expensive and have a life length measured in minutes, why predictions of tool wear are of great interest. Finite Element (FE) simulations have a central role in the development of tools and cutting processes, but performing simulations of metal cutting is not easy. The method chosen for the chip formation has a large impact on the result of the simulations. The scope of this work includes a survey on important parameters and different

Abstract:

Tires are the most influential component of the vehicle as they constitute the only contact between the vehicle and the road and have to generate and transmit forces necessary for the driver to control the vehicle. Hydroplaning is a phenomenon which occurs when a layer of water builds up between the tires of a vehicle and the road surface which leads to loss of traction that prevents the vehicle from responding to control inputs such as steering, braking or acceleration. It has become an extremely important factor in the automotive and tire industry to study the factors affecting vehicle hydr

Safety is an important aspect when designing bridges and roads. One aspect among others to consider is the road restraint systems.

Full-scale test must be performed for a proposed parapet to evaluate the performance. Often several full-scale tests are performed in order to achieve CE-marking, making it an expensive process.

Detta examensarbete använder ett systematiskt tillvägagångssätt för att omkonstruera ett växellådshus till ett elektriskt fordon med avsikt att förbättra prestanda med avseende på hållfasthet, livslängd och styvhet. I examensarbetet ges även en kort beskrivning av hur växellådan fungerar, vilken roll den spelar i de elektriska fordonen, samt grundläggande teori som används vid konstruktion av liknande växellådor. Den huvudsakliga arbetsmetoden som använts för att nå målen är topologioptimering och olika lösningar har simulerats för att förenkla den framtida omkonstruktionen. Analyser av de ol

Abstract:

Joints with pressure perpendicular to the grain are a common occurrence in wooden structures. While the making of such a joint is very simple, dimensioning it is difficult: The load configuration causes a mix of ductile compressive failure and brittle tensile failure. In addition, the global response shows hardening after the first failure. Recent changes to the design code has made the design bearing strength for this type of load so low that Norwegian houses no longer fulfill the requirements. As the houses remain standing even after the new rules were introduced, it is clear that a revision

Abstract:

Proplate, a world leading company, is expert on volume-based cutting and machining of both ordinary steel as well as stainless steel. One of Proplate’s mayor products is tension bars, which is a component made to balance high forces and give stability to structures such as cranes, buildings, bridges and much more. Proplate builds their tension bars in different high strength steel materials, purchased from SSAB, and sells them worldwide. Proplate would like to market themselves better and wishes to produce a catalogue for the maximum load that can be applied to their tension bars, as competito

Abstract:

En raison de leurs excellentes propriétés spécifiques, les matériaux composites à matrice organique sont de plus en plus utilisés dans le secteur des transports. Durant leur vie en service, ces matériaux composites sont souvent soumis à des environnements hygroscopiques agressifs. Dès la phase transitoire du p processus de diffusion, l’absorption d’eau engendre des variations dimensionnelles ainsi que la plastification du réseau polymère, ce qui modifie son comportement mécanique. Ce travail est dédié à la caractérisation expérimentale des lois de comportement hygro-mécaniques des matériaux ét

Abstract:

The current research analyzed the flutter response of the Stonecutters Cable-Stayed Bridge in Hong Kong, which has a twin deck configuration, under the effect of wind. The aerodynamic instability response of the bridge steel deck of the main span is mainly the focus of the current project. Initially, a complete finite element bridge model was created in ABAQUS finite element software, representing all the structural elements of the Stonecutters Cable-Stayed Bridge in a lumped mass bridge model. The natural frequencies and the vibration modes were validated against the data available in the lit

Abstract:

A prototype rigid wall relocatable shelter was designed and constructed using cold-formed steel (CFS) construction techniques including shear walls with corrugated sheathings. The design of the shelter was to be mechanically sound with adequate thermal performance and resistance to corrosion. Modeling of structural shear walls was performed using ABAQUS and verified with experimental results. At the project's conclusion, a completed full-scale prototype shelter was constructed.

Abstract:

Understanding failure mechanics of mechanical equipment is one of the most important aspects of structural and aerospace engineering. Crack growth being one of the major forms of failure in structural components has been studied for several decades to achieve greater reliability and guarantee higher safety standards. Conventional approaches using the finite element framework provides accurate solutions, yet they require extremely complicated numerical approaches or highly fine mesh densities which is computationally expensive and yet suffers from several numerical instabilities such as elemen
