Sammanfattning : The present work is devoted to approximation techniques for singular extremal problems arising from optimal design problems in structural and fluid mechanics. The thesis consists of an introductory part and four independent papers, which however are united by the common idea of approximation and the related application areas. LÄS MER
Sammanfattning : This thesis concerns topology optimization of vehicle structures. Vehicle structures are considered to be composed of beams joined together and the work has been focused on a method for beam topology optimization including joints. LÄS MER
Sammanfattning : Two different techniques are presented for enhancing the thermal performance of natural convection cooled heat sinks. The physics is described by solving the conjugate heat transfer problem with a spectral element method. The temperature distribution is computed in two sub-domains, whose solution is then conjugated.

Sammanfattning : This thesis introduces a topology optimization approach to design, from scratch, efficient microwave devices, such as antennas and waveguide transitions. The design of these devices is formulated as a general optimization problem that aims to build the whole layout of the device in order to extremize a chosen objective function. LÄS MER
Sammanfattning : Fatigue, or failure of material due to repeated cyclic loading, is one of the most common causes of mechanical failures. The risk of fatigue in a load carrying component is often lowered by adding material, thereby reducing stresses. LÄS MER
