El ejemplo de verificación describe las cargas de presión en los muros de los edificios en una disposición en tándem ubicada a nivel del suelo. 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.
Una membrana de globo esférico se llena con gas con presión atmosférica y volumen definido (estos valores se usan solo para la definición del modelo de elementos finitos). Determine the overpressure inside the balloon due to the given isotropic membrane prestress. 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.
Un tubo con una sección tubular está cargado por una presión interna. This internal pressure causes axial deformation of the pipe (the Bourdon effect). Determine the axial deformation of the pipe endpoint.
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. Determine la deformación máxima de la placa sin considerar el peso propio.
Un pilar se compone de una sección de hormigón (rectángulo 100/200) y una sección de acero (perfil I 200). It is subjected to pressure force. Determine the critical load and corresponding load factor. The theoretical solution is based on the buckling of a simple beam. In this case, two regions have to be taken into account due to different moments of inertia and material properties.
Este ejemplo es una modificación del ejemplo de verificación 0061; la única diferencia es que el material del recipiente es incompresible. 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.
Un recipiente de dos capas, de extremos abiertos y paredes gruesas está cargado por una presión interna y externa; por lo tanto, no hay tensión axil. While neglecting self‑weight, the radial deflection of the inner and outer radius, and the pressure (radial stress) in the middle radius is determined.
Cuatro pilares están fijos en la parte inferior y conectados por un bloque rígido en la parte superior. 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.
Determine la flecha máxima del voladizo que consta de dos capas de vidrio y una capa de lámina intermedia. The plate is fully fixed at one end and subjected to uniform pressure.
Un bloque tridimensional hecho de material elástico-plástico está fijado en ambos extremos. The block's middle plane is subjected to a pressure load. The surface plasticity is described according to the Tsai-Wu plasticity theory.
Determinar la flecha máxima de un bloque tridimensional fijo en ambos extremos. 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. The block's middle plane is subjected to vertical pressure.
Determine la flecha máxima de cuatro pilares fijos en la parte inferior y conectados por un bloque rígido en la parte superior. 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.
Un bloque tridimensional hecho de material elástico-plástico con endurecimiento está fijado en ambos extremos. The block's middle plane is subjected to a pressure load. The surface plasticity is described according to the Tsai‑Wu plasticity theory.
