在两个同心圆柱体的两个半径半径之间的各向同性预应力拉伸膜,该预应力位于一个不与竖轴平行的平面上。 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.
定义一个简单振动器,由质量 m(只考虑 x 方向)和刚度为 k 的弹簧组成。 The mass is embedded on a surface with Coulomb friction and is loaded by constant-in-time axial and transverse forces.
在其上端固定一根截面为正方形的拉杆。 The rod is loaded by self-weight. For comparison, the example is also modeled with the concentrated force load, the value of which is equal to the gravity. The aim of this verification example is to show the difference between these types of loading, although the total loading force is equal.
在给定的边界条件下,杆件受到扭矩和轴力。 Neglecting its self-weight, determine the beam's maximum torsional deformation as well as its inner torsional moment, defined as the sum of a primary torsional moment and torsional moment caused by the normal force. Provide a comparison of those values while assuming or neglecting the influence of the normal force. 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).
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.
