AbstractIntroduction to dimensioning (strength calculation) for static and dynamic loaded components and machine parts. Critical strength and fracture criteria. Analytical methods for the calculation of stresses and strains. Consideration of stress concentrations by notch effects. Strength proof for different machine elements.
ObjectiveThe lecture uses basic strength theory from Mechanics II to size and design typical machine elements as beam structures, axes and shafts, pressure vessels, weldings and screws. The students learn to define both geometry and material of frequently used machine elements. Strength calculations are performed both for static and fatigue operating conditions.
Content- Theoretical basics of engineering design
- Description of ductil and brittle material behavior
- Design of machine elements at static loading conditions
- Notch effects
- Axes and shafts
- Fatigue design
- Surface pressure
- Rotationally symmetric bodies, pressure vessels and cylindrical interference
- Dimensioning of permanent and separable joints
