151-0303-00L | Dimensioning I | 3 credits | 3G | E. Mazza, R. Hopf | |

Abstract | Introduction to Dimensioning of components and machine parts. Basic structural theories are introduced and a short introduction to finite elements is given. Further, elements from fracture mechanics, plasticity and stability of structures are presented. | ||||

Objective | The goal of the lecture is to build on and extend the theories from Mechanics 2. Students learn how to implement adequate models for practical dimensioning problems in mechanical engineering and how to solve and critically interpret these models. | ||||

Content | - Basic problem of continuum mechanics - Structural theories - Introduction to finite element methods - Strength of materials - Fatigue - Stability of structures | ||||

Lecture notes | Will be announced during the first lecture. | ||||

Literature | Will be announced during the first lecture. | ||||
