In this lesson, we'll learn about the main types of finite element stiffness used in calculations in the program. Lyre.
Types of stiffness discussed in the lesson:
1. Beam, reinforced concrete section
2. Two channels, metal section
3. Reinforced concrete slab (plate stiffness)
4. Stiffness of a solid (with steel characteristics)
5. Stiffness of a single-node finite element (FE 51)
