Summary
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.

Exercise:
1. Introductory training, requirements, a summary study of literature, summary of the basic knowledge from strength and elasticity, mechanic of continuum and physic of materials necessary for mastering the subject.
2. The basic philosophy of design components and their application in selected manufacturing industries. Application fields for pressure vessels and piping and comparing results using different methods.
3. Practice using some methods of construction material criteria and their application in different loading conditions, the same structural parts,
assessing the impact on the shape of the component selection of a suitable material.
4. Application of criteria for maximum allowable voltage on the profiled element light strained construction to move the wall pressure vessels and general support cross-loaded on the buckling.
5. Solved examples of application of criteria for maximum permissible
deformation safety assessment of structures subjected to creep, examples of election material components with a plastic joint.
6. Examples of design material for structures and low temperature cryogen. Application methods of selection of ceramic materials and glass for its
intended use.
7. The selected design solution of the material in its application to the component exposed to fatigue. Comparison of results of draft material for consideration uniaxial and multiaxial cyclic stress.
8. Solved examples of choices of construction materials for a pair of well- mannered loading and functional interaction surfaces. Comparison of different results design of structural materials for a pair of different mechanisms wear.
9. Examples of design of structural materials under uniaxial and multiaxial stress, special cases of stress-strain states. Practical examples of howstress-strain state influence the choice of construction material.
10. The solution selected examples of the loaded beam, plate and shell on the choice construction material in the condition of minimum weight. Comparison solution results in thin-walled pressure vessel under conditions of "leak before break ".
11. Examples of solving a suitable construction material for the production of springs applying the criteria of maximum strain energy.
12. Examples of the influence of chemical composition and processing
technology construction materials and their resulting microstructure to
draft design index materials.
