Una placa ortótropa cuadrada en capas está completamente fijada en su punto medio y sometida a presión. Compare the deflections of the plate corners to check the correctness of the transformation.
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.
Una viga de madera reforzada con dos placas de acero en los extremos está cargada por presión. The wood fibers are parallel to the upper loaded side of the beam. The plastic surface is described 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.
Una placa ancha con un agujero está cargada en una dirección por la tensión de tracción. The plate width is large with respect to the hole radius, and it is very thin, considering the state of the plane stress.
Una viga de madera reforzada con dos placas de acero en los extremos está cargada por presión. The wood fibers are parallel to the upper loaded side of the beam. The plastic surface is described according to the Tsai-Wu plasticity theory.
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.
