Verifikační příklad popisuje tlaková zatížení na stěny budov v tandemovém uspořádání na úrovni terénu. The buildings are simplified to rectangular objects and scaled down while maintaining the elevation ratios. The pressure distribution on the walls of the model of a medium-high building was conducted by an experiment. The chosen results (pressure coefficient Cp) are compared with the measured values.
A spherical balloon membrane is filled with gas with atmospheric pressure and defined volume (these values are used for FE model definition only). Determine the overpressure inside the balloon due to the given isotropic membrane prestress. K tomu slouží přídavný modul RF-FORM-FINDING. Elastic deformations are neglected both in RF-FORM-FINDING and in the analytical solution; self-weight is also neglected in this example.
A pipe with a tubular cross-section is loaded by internal pressure. This internal pressure causes axial deformation of the pipe (the Bourdon effect). Stanovte axiální deformaci koncového bodu trubky.
A thin rectangular orthotropic plate is simply supported and loaded by uniformly distributed pressure. The directions of axes x and y coincide with the principal directions. Maximální průhyb desky se stanoví bez zohlednění vlastní tíhy.
A thin circular ring of a rectangular cross-section is exposed to external pressure. Stanovíme kritické zatížení a příslušný součinitel zatížení pro vzpěr v rovině.
Tento příklad je modifikací verifikačního příkladu 0061; Jediný rozdíl je v tom, že materiál nádoby je nestlačitelný. An open‑ended, thick‑walled vessel is loaded by both inner and outer pressure. While neglecting self‑weight, the radial deflection of the inner and the outer radius is determined.
Dvouvrstvá silnostěnná nádoba s otevřeným koncem je zatížena vnitřním a vnějším tlakem; proto nevzniká žádné osové napětí. While neglecting self‑weight, the radial deflection of the inner and outer radius, and the pressure (radial stress) in the middle radius is determined.
A timber beam reinforced by two steel plates at the ends is loaded by pressure. The wood fibers are parallel to the upper loaded side of the beam. Plastická plocha je popsána podle teorie plasticity Tsai-Wu.
Ve spodní části jsou upevněny čtyři sloupy, které jsou nahoře spojeny tuhým blokem. The block is loaded by pressure and modeled by an elastic material with a high modulus of elasticity. The outer columns are modeled by linear elastic material and the inner columns by a stress-strain diagram with decaying dependence. Assuming only the small deformation theory and neglecting the structure's self-weight, determine its maximum deflection.

A vertical cantilever with a square cross-section is loaded at the top by tensile pressure. Konzola je z izotropního materiálu. Calculate the deflection.
Na obou koncích je upevněn trojrozměrný blok z elasticko-plastického materiálu. The block's middle plane is subjected to a pressure load. The surface plasticity is described according to the Tsai-Wu plasticity theory.
Stanovíme maximální průhyb čtyř dolních sloupů spojených tuhým blokem nahoře. The block is loaded by pressure and modeled by an elastic material with a high modulus of elasticity. The outer columns are modeled as orthotropic elastic material, and the inner columns as orthotropic elastic-plastic material with the same elastic parameters as the outer columns and plasticity properties defined according to the Tsai-Wu plasticity theory.
