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.
