Zakřivený nosník se skládá ze dvou nosníků obdélníkového průřezu. The horizontal beam is loaded by distributed loading. While neglecting self-weight, determine the maximum stress on the top surface of the horizontal beam.
Jednoduchý oscilátor se skládá z tělesa o hmotnosti m (uvažuje se pouze ve směru osy x) a lineární pružiny s tuhostí k . The mass is embedded on a surface with Coulomb friction and is loaded by constant-in-time axial and transverse forces.
Zděná stěna je vystavena rovnoměrnému zatížení uprostřed své horní části. The Isotropic Masonry 2D material model is compared with the Isotropic Linear Elastic model, with surface stiffness property Without Tension in the nonlinear calculation.
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.

Determine the maximum deflection of a three-dimensional block fixed at both ends. The block is divided in the middle: the upper half is made of an elastic material and the lower part is made of timber - an elasto-plastic othotropic material with the yield surface described according to the Tsai-Wu plasticity theory. Na rovinu procházející středem bloku působí svislý tlak.
A membrane is stretched by means of isotropic prestress between two radii of two concentric cylinders not lying in a plane parallel to the vertical axis. Find the final minimum shape of the membrane - the helicoid - and determine the surface area of the resulting membrane. 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.
