Uma viga curvada é constituída por duas vigas de secção retangular. The horizontal beam is loaded by distributed loading. While neglecting self-weight, determine the maximum stress on the top surface of the horizontal beam.
Um oscilador simples é composto por massa m (a ser considerada apenas na direção x-) e pela mola linear com a rigidez k. The mass is embedded on a surface with Coulomb friction and is loaded by constant-in-time axial and transverse forces.
Uma alvenaria está sujeita a uma carga distribuída a meio da secção superior. The Isotropic Masonry 2D material model is compared with the Isotropic Linear Elastic model, with surface stiffness property Without Tension in the nonlinear calculation.
Nas duas extremidades, está fixado um bloco tridimensional de material elástico-plástico. The block's middle plane is subjected to a pressure load. The surface plasticity is described according to the Tsai-Wu plasticity theory.
Nas duas extremidades, está fixado um bloco tridimensional de material elástico-plástico com endurecimento. 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. O plano central do bloco está sob pressão vertical.
Uma membrana é esticada através de um pré-esforço isotrópico entre dois raios de dois cilindros concêntricos que não se encontram num plano paralelo ao eixo vertical. Find the final minimum shape of the membrane - the helicoid - and determine the surface area of the resulting membrane. The add-on module RF-FORM-FINDING is used for this purpose. Elastic deformations are neglected both in RF-FORM-FINDING and in the analytical solution; self-weight is also neglected in this example.
