In engineering, design refers to the design of components so that they can fulfill their defined purpose. This can affect all aspects of design, construction, manufacture, operation and end of service:
- Application environment with temperature, pressure and humidity
- Atmosphere , d. H. chemical composition of the surrounding gas, if not air
- Loads and collective loads
- Repair options
- Disposal options.
Once decisions have been made about the type of construction , the materials and the shape , the next step is the numerical definition of geometric sizes. This means design and dimensioning .
