This model demonstrates how to use the Interior Contact feature to model the contact pressure at a bolted joint connecting two copper busbars. The AC current flowing through the assembly is induced to flow close to the outside boundaries of the conductors, but the contact resistance is ... 詳細を見る
Trusses are structural members that can only sustain axial forces, but no bending or torsion. In the following example you first build and solve a simple 2D truss model using the 2D Truss interface. Later on, you analyze a 3D variant of the same problem using the 3D Truss interface. This ... 詳細を見る
The Highly Accelerated Stress Test (HAST) is a testing technique to precipitate failure of electronic devices under elevated temperature and high humidity environment. This model demonstrates the structural analysis of a plastic encapsulated IGBT module under the HAST testing condition. ... 詳細を見る
The ball grid array (BGA) technology is a surface-mount technology widely used in electronic packaging. Usually, there are two types of solder balls considered in the array, including the functional balls that are required for electric connections and the support balls that are used only ... 詳細を見る
A steel ball is pressed down against a rubber membrane. When the contact pressure exceeds a certain value, the two parts start sticking together. When the ball is retracted, the membrane is pulled upwards in the bonded region. During the retraction, the bond is partially broken. This ... 詳細を見る
This model showcases how to solve for the scattered field when knowing the incident field for three different types of scatterer, i.e. an infinitely rigid one, a cavity and an elastic inclusion. This formulation can be useful when the scatterer is in the far-field of the source, such ... 詳細を見る
This benchmark studies the nonlinear deformation of a spherical cap subjected to point load at center using 2D axisymmetric Solid Mechanics and Shell interfaces. The results from the Shell interface are compared with Solid Mechanics interface as well as with analytical results given in ... 詳細を見る
This model describes the pressure wave propagation in a muffler for an internal combustion engine. The purpose of the model is to show how to analyze both inductive and resistive damping in pressure acoustics as well as coupling the fluid to the surrounding elastic shell structure of the ... 詳細を見る
This example shows how to compute the critical buckling load in the presence of dead loads. A truss tower is supported by pretensioned guys. The pretension load and gravity on the truss are considered as dead loads, while the vertical load applied at the top of the tower is considered ... 詳細を見る
This example presents a homogenized model of a corrugated sheet based on a unit cell approach. The numerically obtained equivalent stiffness matrices are compared with various analytical models. Two corrugation profiles, trapezoidal and round, are considered in this example. 詳細を見る
