Summary

The course is dealing with basic mechanical properties, like elasticity, strength, plasticity and toughness. Their relationships to structure and processing of materials, especially metals, are discussed. The attention is also paid to another important properties, for e.g. resistance to cyclic loading and heat resistance. Students are informed about basic testing methods in accordance with the appropriate standards, in areas of both destructive and nondestructive testing.
