101-0187-00L | Structural Reliability and Risk Analysis | W | 3 credits | 2G | B. Sudret | |

Abstract | Structural reliability aims at quantifying the probability of failure of systems due to uncertainties in their design, manufacturing and environmental conditions. Risk analysis combines this information with the consequences of failure in view of optimal decision making. The course presents the underlying probabilistic modelling and computational methods for reliability and risk assessment. | |||||

Objective | The goal of this course is to provide the students with a thorough understanding of the key concepts behind structural reliability and risk analysis. After this course the students will have refreshed their knowledge of probability theory and statistics to model uncertainties in view of engineering applications. They will be able to analyze the reliability of a structure and to use risk assessment methods for decision making under uncertain conditions. They will be aware of the state-of-the-art computational methods and software in this field. | |||||

Content | Engineers are confronted every day to decision making under limited amount of information and uncertain conditions. When designing new structures and systems, the design codes such as SIA or Euro- codes usually provide a framework that guarantees safety and reliability. However the level of safety is not quantified explicitly, which does not allow the analyst to properly choose between design variants and evaluate a total cost in case of failure. In contrast, the framework of risk analysis allows one to incorporate the uncertainty in decision making. The first part of the course is a reminder on probability theory that is used as a main tool for reliability and risk analysis. Classical concepts such as random variables and vectors, dependence and correlation are recalled. Basic statistical inference methods used for building a probabilistic model from the available data, e.g. the maximum likelihood method, are presented. The second part is related to structural reliability analysis, i.e. methods that allow one to compute probabilities of failure of a given system with respect to prescribed criteria. The framework of reliability analysis is first set up. Reliability indices are introduced together with the first order-second moment method (FOSM) and the first order reliability method (FORM). Methods based on Monte Carlo simulation are then reviewed and illustrated through various examples. By-products of reliability analysis such as sensitivity measures and partial safety coefficients are derived and their links to structural design codes is shown. The reliability of structural systems is also introduced as well as the methods used to reassess existing structures based on new information. The third part of the course addresses risk assessment methods. Techniques for the identification of hazard scenarios and their representation by fault trees and event trees are described. Risk is defined with respect to the concept of expected utility in the framework of decision making. Elements of Bayesian decision making, i.e. pre-, post and pre-post risk assessment methods are presented. The course also includes a tutorial using the UQLab software dedicated to real world structural reliability analysis. | |||||

Abstract | This course will provide a solid foundation for understanding physical principles of THz applications. We will discuss various building blocks of THz technology - components dealing with generation, manipulation, and detection of THz electromagnetic radiation.

Objective | This is an introductory course on Terahertz (THz) technology and applications. Devices operating in THz frequency range (0.1 to 10 THz) have been increasingly studied in the recent years. Progress in nonlinear optical materials, ultrafast optical and electronic techniques has strengthened research in THz application developments. Due to unique interaction of THz waves with materials, applications with new capabilities can be developed. In theory, they can penetrate somewhat like X-rays, but are not considered harmful radiation, because THz energy level is low. They should be able to provide resolution as good or better than magnetic resonance imaging (MRI), possibly with simpler equipment. Imaging, very-high bandwidth communication, and energy harvesting are the most widely explored THz application areas. We will study the basics of THz generation, manipulation, and detection. Our emphasis will be on the physical principles and applications of THz in the domain of imaging, communication and energy harvesting. | |||||

151-0349-00L | Fatigue Strength of Materials, Components and Structures | W | 4 credits | 3G | M. Guillaume, R. E. Koller | |

Abstract | Fatigue of materials is playing a key role in light weight structures. All applications are affected that are exposed to oscillating loads. The lecture will present the most important methods for analyzing the fatigue strength under service load conditions. This starts with the conventional assessment of a components endurance limit and ends with the application of the damage tolerance philosophy. | |||||

Objective | Goals of the lecture An introduction to the most important terms and phenomena related to fatigue damages of metallic components will be given and explained by practical examples. Methods for assessment of endurance strength, finite life fatigue strength, crack initiation and crack growth will be discussed. The lecture shall demonstrate how to solve fatigue problems in practice. Examples like the ICE disaster at Eschede or structural problems of the Combino tram demonstrate the significance of this subject. The fatigue behavior of lightweight structures for vehicles and aircrafts has to be considered during the component design process. Designing the static strength of a component alone is not sufficient since fatigue damages of such components may cause extremely high costs. Structural components of modern aircraft like Airbus A380 or A400M are designed with respect to crack growth using the damage tolerance philosophy. Understanding fatigue strength and its phenomena requires broad knowledge of material behavior, services loads, manufacturing effects as well as of analysis and test methods. Fatigue strength is a highly interdisciplinary area of work. For this the most important tools and methods shall be presented. | |||||

Abstract | Ropeways represent a public transport system where steel wired ropes play a central role. Such systems come to a favorite transport solution when the costs for conventional systems become out of scale due to difficult and impossible terrestrial surface (alpine terrain). Additionally ropeways are environment friendly, very energy efficient and offer a very high safety level. | |||||

Objective | Cable cars make use of extensive mechanical systems, which because of their operational location, are exposed to difficult meteorological and topographical conditions. In order to guarantee the requisite safety and reliability of the equipment, the components and their interaction in the system must fulfil stringent functional requirements. This is particularly the case because of the significant distance (2-4km) between the individual structures. The lectures with related exercises offer an excellent opportunity to apply the learned theoretical basic principles of mechanics and engineering in plant construction. Not only the function and resistance of individual components will be studied, but also complex interactions, which are imperative for the safe and smooth running of the equipment. It also includes the teaching of the basics of project planning and design, as well as the evaluation of systems in a distinctly interdisciplinary manner. For the manufacturer of a cable car installation the integration of sub-assemblies making use of very different technologies always poses a particular challenge. For this reason, the methodology for the handling of these typical engineering assignments is important and makes up a significant part of the lecture content. | |||||
