4. Cracks, cracks localization, fracture energy, modelling of concrete in tension.
5. Plane state of stress, concrete crushing. Methods of solution of non-linear equations system.
6. Methods of non-linear task solution: layered, integral.
7. Non-linear modelling of flat concrete structures.
8. Non-linear analysis of prestressed concrete sections. Optimisation of reinforcement design into a section.
9. Non-linear material models of concrete and reinforced concrete in some comercial software of FEM systems.

Syllabus
1.–3. Calculation analysis of the cross section bearing capacity loaded by combination of bending moment and normal force – physical non-linearity of the concrete and steel. Cross section layer model for compression part. Algorithm development of the calculation with help of Microsoft Excel program.
4. Correction.
5.–6. Deflection computation of the two way slab within Scia Engineer computing program with the help of non-linear calculation.
7. Correction.
8.–9. Deflection computation of the two way slab within Scia Engineer computing program with help of linear iterative computation – non-linear behaviour is taken into account by modification of the stiffness matrix within every iterative step.
10. Tasks submission. Credit.
