Structural Analysis Presentation, General Introduction
This presentation gives an overview of the capabilities of COMSOL Multiphysics within the area of structural analysis.
The presentation mostly covers the functionality of the Structural Mechanics Module - but also touches on what is available in the MEMS Module and the Acoustics Module....

Blood Vessel
This model refers to a portion of the vascular system of a young child - the upper part of the aorta artery. The blood vessels are embedded in a biological tissue (the cardiac muscle) and, during the flow of blood, pressure is applied to the internal surfaces producing deformation of the vessel wall...

Hyperelastic Seal
Loads that depend on the deformation are often termed follower loads. The most common case is a pressure directed along the normal to a surface which deforms. In general, both the direction of the load and the area of the loaded surface will change.
This model studies the force-deflection relati...

Parameterized I-Beam
This example shows how to parameterize a CAD model by deforming the corresponding finite element mesh.
The method enables geometry parameterization of non-parameterized CAD models such as:
- models created by the built-in COMSOL CAD tools
- imported neutral CAD files such as .igs...

Fluid-Structure Interaction in Aluminum Extrusion
In massive forming processes like rolling or extrusion, metal alloys are deformed in a hot solid state with material flowing under ideally plastic conditions. Such processes can be simulated effectively using computational fluid dynamics, where the material is considered as a fluid with a very high...

Viscoplastic Creep in Solder Joints
This example studies viscoplastic creep in solder joints under thermal loading using the Anand viscoplasticity model, which is suitable for large, isotropic, viscoplastic deformations in combination with small elastic deformations.
The model geometry includes two electronic components (chips) mou...

Structural and Fatigue Analysis of a Car Wheel Rim
This example shows two structural analyses of a car wheel rim.
Firstly, the parametric solver is used to simulate a varying load along the boundary of the rim. The model solves for both the anti-symmetric and symmetric load cases. The two solutions are then combined in MATLAB in order to retrieve...

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 field i...

Thermal Drift in a Microwave Filter Cavity
Microwave filters are used to eliminate unwanted frequency components in the output from microwave transmitters. They are typically inserted between a power amplifier and an antenna. The amplifiers are nonlinear and produce harmonics that must be eliminated with filters that have a rather narrow pa...

Elasto-plastic and Fatigue Analyses of a Cylinder with Hole
A load-carrying component of a structure is subjected to multi-axial cyclic loading during which localized yielding of the material occurs.
Due to localized yielding, you can use two methods to obtain the stress and strain distributions for the fatigue law. The first method is an elasto-plastic a...
