Thermal Initial Stresses in a Layered Plate

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 thermal stresses are induced due to the difference ... Read More

Connecting Beams and Solids

This example demonstrates the use of the **Solid-Beam Connection** multiphysics coupling to create transitions between the Solid Mechanics and Beam interfaces. Two different connection types are discussed, and a comparison of the stress distributions at the transition is made. Read More

Vibroacoustic Loudspeaker Simulation: Multiphysics with BEM-FEM

This model shows a full vibroacoustic analysis of a loudspeaker including driver, cabinet, and stand. It lets you apply a nominal driving voltage and extract the resulting sound pressure level in the cabinet and in the outside room, as well as the deformation of the cabinet and driver, ... Read More

Nonlinear Magnetostrictive Transducer

Magnetostrictive transduction is used in sonars, acoustic devices, active vibration, and position control and fuel injection systems. The transducer has a steel housing enclosing a drive coil. A magnetostrictive material is placed in the core, which works as an actuator when a magnetic ... Read More

Thermal Stress Analysis of a Turbine Stator Blade

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 loads asserted by the fluid rushing through the ... Read More

Mixed-Mode Debonding of a Laminated Composite

Interfacial failure by delamination or debonding can be simulated with a Cohesive Zone Model (CZM). This example shows the implementation of a CZM with a bilinear traction-separation law. It is used to predict the mixed-mode softening onset and delamination propagation in a composite ... Read More

Static and Eigenfrequency Analyses of an Elbow Bracket

The component depicted in this model is part of a support mechanism and is subjected to various mechanical loads. This tutorial model takes you through the steps to carry out a detailed analysis of the part using the Structural Mechanics Module. In the various parts of the example you ... Read More

Generation of Random Surfaces

These examples demonstrate how to generate randomized geometric surfaces. The COMSOL Multiphysics® software provides a powerful set of built-in functions and operators, such as functions for uniform and Gaussian random distributions and a very useful sum operator. In the blog ... Read More

Wave Propagation in Rock Under Blast Loads

Transient analysis of the wave propagation in rock mass caused by a short duration load on the surface. Such loads are typical during tunnel constructions and other excavations using blasting. The model shows the use of the Low-reflecting boundary conditions to truncate the ... Read More

Eigenfrequency Analysis of a Free Cylinder

This model calculates the eigenfrequencies and mode shapes of an unconstrained cylinder in axisymmetry. The model is taken from NAFEMS Free Vibration Benchmarks. The eigenfrequencies are compared with the values given in the benchmark report. Read More
