16. Dynamic Equations for Spherical, Orthotropic and Piezoelectric Cylindrical Shells Using the Power Series Method
Sammanfattning : Shells are commonly used in many branches of engineering, and have therefore beeninvestigated for a number of different types of shells. A shell is considered to be curved aplate with small thickness compared both to the other geometrical dimensions as well asto the wavelengths of importance. LÄS MER
17. Experimental and Numerical Investigations of Flames Stabilized by Swirl Flow and Bluff-body:Flame Structures and Flame Instabilities
Sammanfattning : Combustion and its control are essential to our existence on this planet since we knew it. Nowadays, the largest share of the world’s electricity and most of our transportation systems are powered by combustion. In addition, industrial processes also rely heavily upon combustion. LÄS MER
18. Analysis of Conformal Antennas and Periodic Structures
Sammanfattning : In the last decades much attention has been paid to the design of high-performance antennas. Accurate control of the radiation properties is very important in electromagnetic engineering applications. LÄS MER
19. Dynamics of Structures with Thin Piezoelectric Layers
Sammanfattning : The subject of this thesis is dynamics of structures with thin piezoelectric layers. Piezoelectric materials are used in sensor and actuators and common applications for these are vibration damping, ultrasonic transducers, buzzards and more. LÄS MER
20. On Postbuckling Analysis of Thin-walled Structures Numerical and Statistical Approaches
Sammanfattning : Thin-walled structural elements, such as plates, shells and beams are important load carrying components in civil-, mechanical-, automotive- aeronautical- and marine engineering structures. In order to reduce the weight thin-walled structures are given an optimum design making them sensitive to unforeseen deviations in geometry, boundary conditions, material properties and applied loads.
