Abstract:
Since performances of experimental and numerical tools have been largely improved, mechanics of materials can explore smaller and smaller scales. Thus, a better comprehension, or even a prediction, of local phenomena associated with macroscopic deformations are hoped. This dissertation focuses on the smallest scale involved in mechanical behavior of materials, i.e. interactions between nuclei due to electrons behavior and especially to valence electrons. The originality of this work is setting up the finite element method as numerical tool to solve this problem. This approach largely used to s

The objective of this study was the development of a procedure in GT STRUDL to design reinforced concrete flat plate systems based on the results of finite element analysis. The current state-of-practice of reinforced concrete flat plate design was reviewed, including the ACI direct design and equivalent frame techniques, the yield line method, and the strip design method. The principles of these methods along with a critical evaluation of their applicability and limitations were presented as motivation for a finite element based design procedure.

Abstract:
In this dissertation we consider the valuation of discretely monitored barrier options under the in nite element method. The in nite element method is an extension to the standard nite element method that accepts problems with unbounded spacial domains (such as the Black-Scholes PDE), without resorting to domain truncation. The degeneracy of the Black-Scholes PDE when the underlying asset reaches zero, requires that the method be formulated within the context of weighted Sobolev spaces. We will demonstrate the convergence of the proposed method and provide a rigorous investigation int

Abstract:
The use of lightweight construction in building applications offers flexibility in use and ease of construction but often goes hand in hand with reduced sound insulation. Regarding this issue, this thesis investigates sound transmission behaviour of such structures. A numerical model is developed using a coupled waveguide finite element-boundary element (WFBE) method to predict the transmission loss (TL) of more complex structures and is applied to double panel systems. Initially, analytical waveguide models for a plate strip are developed. These models are used to gain insight into the vibro-

Instead of producing specific active-element patterns an average active-element pattern could be created and then applied that to the array.<br /><br />The average active-element pattern can be used for every element in the array wi

Moveable bridges in Florida typically use open steel grid decks due to the weight limitations.

Replacing open steel grid decks that are commonly used in moveable bridges with a low-profile FRP deck can improve rider safety and reduce maintenance costs, while satisfying the strict weight requirement for such bridges.
