Applying a pure torque to a circular shaft should produce torsional deformation without bending. However, a finite element model may show an unexpected bending component even when the geometry, loading direction, and boundary conditions appear correct. This article uses a simple circular shaft to demonstrate how an automatically generated mesh can introduce a small unbalanced … Continue reading When a Pure Torque Causes Bending: The Limitation of Automatic Meshing in SolidWorks Simulation and a Comparison with Ansys Mechanical
Mapped meshing
Examples of 3D Mapped Meshing
In the last post, some examples of 2D mapped meshing are given. Here we are going to look at some examples of 3D mapped meshing. Similar to 2D mapped meshing, the strategy is straightforward: divide the domain in such a way that all the subdomains meet certain requirements, specify the element size or the number … Continue reading Examples of 3D Mapped Meshing

The stress-strain curve of rubber material stiffened by carbon fiber
Fig.1. Illustration of the discretization and BCs A 2D model is created. Plane elements and beam elements are used to discretize rubber material and carbon fiber, respectively. To ensure that rubber and carbon fiber deform together (no slipping), plane elements and beam elements share common nodes. A concentrated force (the red arrow in Fig.1) is … Continue reading The stress-strain curve of rubber material stiffened by carbon fiber
