Institute for Applied Materials – Materials Science and Engineering

Product Development - Component Dimensioning


The aim of the lecture is to present the topics of the dimensioning and the material science in their connection and to learn how to deal with corresponding methods and the combination thereof.

For the prospective engineer the most important educational objective is to understand the interaction of these topics while the interplay of the individual material stresses in the component are clarified.

 The topics in detail are

 Structural dimensioning: basic stresses, superimposed stresses, notch influence, fatigue limit, fatigue strength, assessment of cracked components, operational strength, residual stresses, high temperature stress and corrosion

Material selection: Basics, material indices, material selection diagrams, Ashby procedure, multiple boundary conditions, target conflicts, shape and efficiency.

Learning target: The students…

     are capable to design and dimension components according to their load.

    can include mechanical material properties from the mechanical material test in the dimensioning   process.

    can identify superimposed total loads and critical loads on simple components and to compute them.

    acquire the skill to select materials based on the application area of the components and respective loads.

Examination: written exam (2 hours)
