Vibrating String

Application ID: 8535


This model studies the natural frequencies of a pre-tensioned string using the 2D Truss interface. This is an example of “stress stiffening”; in fact the transverse stiffness of truss elements is directly proportional to the tensile force. Strings made of piano wire have an extremely high yield limit, thus enabling a wide range of pre-tension forces. The results are compared with the analytical solution.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
