Bachelorarbeit aus dem Jahr 2014 im Fachbereich Ingenieurwissenschaften - Allgemeines, Note: 1,0, Universitat Siegen (Lehrstuhl fur Festkorpermechanik), Sprache: Deutsch, Abstract: In den Ingenieurswissenschaften spielt Bauteilversagen durch Rissausbreitung eine wichtige Rolle. In der letzten Zeit bekommen Risssimulationen im Rahmen der linear-elastischen Bruchmechanik mit Hilfe der Phasenfeldmethode zunehmend Aufmerksamkeit. In der vorliegenden Arbeit wird hierzu die Variationsgleichung fur sprode, quasi-statische Rissausbreitung nach BOURDIN mittels Finite Elementen Methoden umgesetzt. Die...

Scientific Essay from the year 2016 in the subject Engineering - Mechanical Engineering, grade: A, KTH Royal Institute of Technology (School of Engineering Sciences), course: Applied Computational Fluid Dynamics, language: English, abstract: Concentrating Solar Power Receiver (CSPs) collect solar radiation with large mirrors and reflect them concentrated on a receiver. Here, a Dish-Stirling type thermal cycle is driven. One of the key preconditions for a cost competitive production of power is a good efficiency factor. Within the framework of this project, we want to examine and qualitatively...

Scientific Essay from the year 2016 in the subject Engineering - Mechanical Engineering, grade: A, KTH Royal Institute of Technology (School of Engineering Sciences), course: Experimental Structure Dynamics, language: English, abstract: Within the framework of this project, the dynamic behaviour of a sub frame sup- porting the rear differential of vehicles is investigated. The original structure, consisting of sub frame and assembled gear, used hard plastic bushings. This setup caused noise inside the passenger cabin, which was not tolerated by customers. In order to obtain a better...
