Portal Cranes are common when handling heavy loads. In this example, the Beam interface is used to compute the stresses in a portal crane designed for lifting 15 tons. Three load cases are considered: self weight, payload, and thermal expansion on a hot summer day. An internal hinge ... Mehr lesen
This example studies the natural frequencies of a pretensioned membrane exhibiting stress stiffening. The model results are compared with the analytical solution. Two different techniques for generating the prestress are explored. Mehr lesen
This tutorial model demonstrates the use of dynamic cyclic symmetry with postprocessing on the full geometry. A 3D impeller with eight identical blades can be divided into eight sectors of symmetry. The model computes the fundamental frequencies for the full impeller geometry and ... Mehr lesen
This example explores the shift in natural frequencies caused by changing the temperature. One study investigates a doubly clamped beam where both ends are fixed, while the other study looks at a cantilever beam where only one end is fixed. The following effects are studied: Stress ... Mehr lesen
This model analyzes the thermal expansion in a MEMS device, such as a microgyroscope, where thermal expansion should be minimized. The device is made from the copper-beryllium alloy UNS C17500 and uses temperature-dependent material properties from the Material Library. The purpose of ... Mehr lesen
In this example, the eigenmodes of a structural damper are computed. In the damper, most of the deformation is controlled by the viscoelastic domains, which have strongly frequency-dependent stiffness and damping properties. This leads to a nonlinear eigenfrequency problem, which can be ... Mehr lesen
Including circumferential displacements in a 2D axisymmetric Solid Mechanics interface allows to compute twist and bending deformations. This model determines stress concentration factors for a hollow shaft for load cases of axial extension, torsion, as well as bending, using a ... Mehr lesen
A cable is a structural member which has stiffness only in its tangential direction, but virtually no bending stiffness. When supported only at its two ends it deflects under gravitational load forming a curve known as catenary. This example shows how to model components such as cables, ... Mehr lesen
An acoustic point source emits a pressure wave in water that travels toward a piece of glass. Cracks are formed and propagate due to high tensile stresses developed in the glass. A fully coupled acoustic-structure interaction problem including phase field damage in solids is solved in ... Mehr lesen
As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... Mehr lesen
