Subject aims expressed by acquired skills and competences

- Knowledge of procedures in creation of a new product - Design of the product reliability and its system solution - Select material according to the maximum allowable stress - Select the material according to the chosen value of the design index - Select material according to the maximum permissible or allowable deformation - Optimize the shape of structural components as dictated by the material - Analyze the function of structural components and propose design criteria for the production of materiál

Teaching methods



Interpretation of design methods of structural parts and methods how to create criteria for materials selection are followed by formulations of maximum stress and maximum strain criteria, of criteria for materials safety against low energy fracture, of materials selection criterion for structural parts.
