Short description

Elastostatics deals with the deformation that results in a component due to loads. In the case of machine elements, students are familiarised with the dimensioning elements used in systems engineering. The design guidelines provide assistance in the correct design of components.

Learning objectives (competencies)

Objectives Elastostatics Competences Taxonomy levels
You will learn how to analyze the stress and distortion state for plane problems and how to determine the stresses and distortions for different cutting directions. F, M K3
You will learn how to determine the stress from the distortion quantities. You will learn about the strength hypotheses that can be used to assess the stress of the material in a spatial stress state F, M K4
You will learn the basic equations of beam theory and will be able to determine the deflection of beams and the resulting stresses. F, M K3,K4
You know the basic equations of torsion and can apply them to case studies. F, M K3
Objectives Machine Elements / Design    
You know the most important machine elements such as bearings, connections and gears. You also know what to look for when selecting them. F, M K3
They are able to roughly dimension the most important machine elements. F, M K4
They know the most important design guidelines and are able to create simple constructions professionally. F, M K3

Module contents

1. Elastostatics:
  • Planar stress state
  • state of distortion, law of elasticity
  • moments of inertia of area
  • Bending, normal stresses
  • Bending line Single field beam
  • Bending line, several fields
  • Torsion, cylindrical shafts
  • Torsion, thin-walled closed and open profiles

2. Machine Elements / Design
  • Bearings
  • Shaft-hub connections
  • Gearbox
  • Connection technology
  • Design guidelines
  • Tolerances and fits
  • Production Engineering

Exercises are distributed, which have to be solved independently and are then discussed in the lecture.
