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.
