| 327-0206-00L | Mechanics | 5 credits | 3V + 2U | T. A. Tervoort, R. Style | |
| Abstract | The aim of this lecture is to introduce strength theory: the mathematical way of describing the mechanical behavior of materials and structures. Concepts such as stresses and distortions, elasticity, viscoelasticity, plasticity and fracture mechanics are taught, mostly in self-study, and applied in exercises. | ||||
| Learning objective | The goal of this lecture is to provide the student with an introduction to the theory and application of the principles of mechanics of materials. In this lecture, the prerequisites for the analysis of deformable bodies are developed, including advanced numerical methods, so that the students can subsequently use them in real-life problems. | ||||
| Content | Stress and strain tensor, linear elasticity and viscoelasticity, torsion, bending, transverse shear, pressure vessels, circles of Mohr, trusses, deflection of beams, buckling of beams, plasticity, fracture mechanics and fatigue. Application of the finite element method for solving inhomogeneous stress problems. | ||||

| 327-3002-00L | Materials for Mechanical Engineers | 4 credits | 2V + 1U | R. Spolenak, A. R. Studart, R. Style | |
| Abstract | This course provides a basic foundation in materials science for mechanical engineers. Students learns how to select the right material for the application at hand. In addition, the appropriate processing-microstructure-property relationship will lead to the fundamental understanding of concepts that determines the mechanical and functional properties. | ||||
| Learning objective | At the end of the course, the student will able to: • choose the appropriate material for mechanical engineering applications • find the optimal compromise between materials property, cost and ecological impact • understand the most important concepts that allow for the tuning of mechanical and functional properties of materials | ||||
