Exercise:

1st Introductory training, requirements, a summary study of literature,
summary of the basic knowledge of strength and elasticity, continuum mechanics and
fyzikymateriálů necessary for mastering the subject.
2nd 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.
3rd 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.
4th 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.
5th 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.
6th Examples of design material for structures and low temperature cryogen. Application
methods of selection of ceramic materials and glass for its intended use.
7th 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.
8th 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.
9th Examples of design of structural materials under uniaxial and multiaxial stress,
special cases of stress-strain states. Practical examples of how
stress-strain state influence the choice of construction material.
10th 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 ".
11th Examples of solving a suitable construction material for the production of springs
applying the criteria of maximum strain energy.
12th Examples of the influence of chemical composition and processing technology
construction materials and their resulting microstructure to
draft design index materials.
13th Test Test.
14th Checking test results, credit.
