Данный контрольный пример основан на контрольном примере 0122. A single-mass system without damping is subjected to an axial loading force. An ideal elastic-plastic material with characteristics is assumed. Determine the time course of the end-point deflection, velocity, and acceleration.
Колонна состоит из бетонного сечения (прямоугольник 100/200) и стального сечения (профиль 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.
Шарнирно опертая балка с прямоугольным сечением, подверженная распределенной нагрузке, смещается в вертикальном направлении за счет эксцентриситета. Considering the small deformation theory, neglecting the self‑weight, and assuming that the beam is made of isotropic elastic material, determine the maximum deflection.
Кирпичная стена подвержена распределенной нагрузке в середине своего верхнего сечения. The Isotropic Masonry 2D material model is compared with the Isotropic Linear Elastic model, with surface stiffness property Without Tension in the nonlinear calculation.
Четыре колонны закреплены снизу и соединены жестким блоком наверху. 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.
Вертикальная консоль квадратного сечения нагружена сверху растягивающим давлением. The cantilever consists of an isotropic material. Calculate the deflection.
Рассмотрим соединение труб строительных лесов, подверженное действию осевой силы и момента. Self-weight is not considered. The material of the tube is idealized as perfectly rigid. All geometrical non-linearities are ignored. Determine the angle of deflection.
Теперь можно определить максимальный прогиб трехмерного блока, защемленного на обоих концах. 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.
Определите максимальный прогиб четырех колонн, закрепленных снизу и соединенных жестким блоком сверху. 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.
Определение максимальных прогибов блока с учетом или без учета действия сдвига. The square block of the isotropic material is fully fixed at one end and loaded with uniform vertical pressure.
