一个矩形截面的悬臂梁,采用弹性 Winkler 基础,并施加均布荷载。 The image shows the calculation of the maximum deflection and maximum bending moment.
在一根方形截面的钢梁上施加轴力和均布荷载。 The image shows the calculation of the maximum bending deflection and critical load factor according to the second-order analysis.
对该钢梁施加铰接,并在另一端进行弹簧支承。 Two cases with different spring stiffnesses are considered. The verification example solves the calculation of the load factors of the beam in the image using the linear stability analysis.
一层正交各向异性方形板的中点完全固定,并施加压力。 Compare the deflections of the plate corners to check the correctness of the transformation.
在悬臂梁中,其纤维不沿梁轴线方向延伸,截面为方形,受拉。 Calculate the maximum deflection.
在两端固定一个三维的弹塑性材料块。 The block's middle plane is subjected to a pressure load. The surface plasticity is described according to the Tsai-Wu plasticity theory.
计算两端固定的三维试块的最大挠度。 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.
计算底部四根柱子的最大挠度, 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.
一个悬臂梁,完全固定在左端,在其右端施加横向力和轴向力。 The tensile strength is zero and the behavior in the compression remains elastic.
四根固定在底部的立柱,上部通过一个刚性试块相互连接。 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.
对该截面为方形的竖向悬臂梁施加拉力, The cantilever consists of an isotropic material. Calculate the deflection.
梁在左端完全固定(限制翘曲),在右端由叉形支座支承(允许翘曲)。 The beam is subjected to a torque, longitudinal force, and transverse force. Determine the behavior of the primary torsional moment, secondary torsional moment, and warping moment. The verification example is based on the example introduced by Gensichen and Lumpe.
左端支承一个 I 形截面的悬臂梁,图中显示了扭矩荷载。 The aim of this example is to compare the fixed support with the fork support and to investigate the behavior of some representative quantities. Comparison is also made to the solution by means of plates. Small deformations are considered, and the self-weight is neglected. Determine the rotation in the midpoint of the cantilever, and in case of the member entity with warping, determine the values of the primary torsional moment, the secondary torsional moment, and the warping moment both on the left end (point A) and the right end (point B).
