1. Properties of plastics from the perspective of product design, influence of temperature, load duration, short-term, time dependent mechanical behaviour. 2. Technological aspects, residual deformations/stresses. 3. Shape design from the point of stiffness and load capacity, ribs of injection-moulded products. 4. Snap fits, mechanical design, technological aspects. 5. Pipe lines, compensations. 6. Tension/compression of composite bars, long fibres reinforcement - stiffness, strength, effect of temperature. 7. Technical theory of bending of composite beams, sandwich elements, optimisation, bimodularity. 8. Non-linear bending, ultimate bending moment, principle of ultimate load design. 9. Ultimate bending moment of one-axis symetrical sections, different yield points in tension and compression. 10. Calculation of ultimate loads, statical - kinematical approach. 11. Ultimate conditions in sections loaded by combination bending moment and axial force, statically admissible diagrams of dividing of internal forces. 12. Rubber/metal springs, linear, rotationally symmetrical case of simple shear, rotational shear. 13. Compresive springs, shape factor, shaping function. 14. Strain energy density of small deformations, compressibility, finite deformations of elastomers, hyperelastic behaviour of elastomers.
