Learning goals: to be able to:

• Define, explain and apply physical and mechanical properties (weight, strength, elasticity, strain, yield, contraction, expansion, conduction, corrosiveness, fatigue, cracking etc)
• Distinguish between construction materials (steels, aluminium, composites) on the basis of their main characteristics (density, strength, elasticity, price, corrosiveness etc) and apply methods for choosing between the different types and variants of these materials.
• Understand the impact of chemical composition, steel production process and crystal structure upon the mechanical properties for high tensile steel, corrosion resistant steel, TMCP, steel for low temperatures etc.
• Understand the impact of load and environment (salt, heat, etc) on the material properties,
• Understand the steel production process,
• Understand the impact of fabrication processes (bending, pressing, welding  etc) on the changes of mechanical properties in view of strength, hardness, fatigue, brittle fracture etc.
• Understand the main aspects of aluminium related to its production process, chemical composition, welding etc.
• Distinguish between different kinds of matrix and reinforcement materials in view of aspects like price, strength, modulus of elasticity, applicability etc, and calculate the mechanical properties of composites using the rule of mixtures.
