These models are used for an introduction to structural mechanics modeling using the structural mechanics module. The following features are introduced: - The Fundamentals: A Static Linear Analysis - Parametric study - Including...
The conditions within gas turbines are extreme. The pressure can be as high as 40 bar, and the temperature more than 1000 K. Any new component must therefore be carefully designed to be able to withstand thermal stresses, vibrations and...
The thermal stress in a layered plate is studied in this example. A plate consisting of two layers, a coating and a substrate layer is stress and strain free at 800 degrees C. The temperature of the plate is reduced to 150 degrees C and...
A classical flow pattern is the von Kármán vortex street that can form as fluid flows past an object. These vortices may induce vibrations in the object. This problem involves a fluid-structure interaction where the large deformation...
Liquid or gas acoustics coupled to structural objects such as membranes, plates or solids are important applications in many engineering fields. This model is a general demonstration of an acoustic fluid phenomenon in 3D that is...
The drive for miniaturizing electronic devices has resulted in today’s extensive use of surface-mount electronic components. An important aspect in electronics design and the choice of materials is a product’s durability and lifetime....
Several numerical algorithms exist to tackle structural contact problems. The one used in COMSOL Multiphysics is based on the so-called Augmented-Lagrangian method. An alternative approach presented in this example model is called the...
A contactor wedge is subject to a gravity load and is forced to slide due to a boundary load over a rigid target wedge surface, both infinitely wide. Horizontal linear springs are also connected between the left vertical boundary and the...
This model deals with the stability of a plate with an edge crack that is subjected to a tensile load. To analyze the stability of exciting cracks, fracture mechanics can be utilized. A commonly used parameter in fracture mechanics,...
The natural frequencies of a prestressed circular membrane are computed and compared with analytical solutions. Two method are used: In the first study the prestress is given explicitly, while in the second study an external load provides...
