Parameter Estimation for a Tensile Test
Application ID: 88761
The model shows how to estimate the Young's modulus and Poisson ratio based on a tensile test. The test measures the tensile force and the radial displacement for different values of the prescribed displacement. The model is based on synthetic data generated in the model itself. It is considered good practice to test parameter estimation models in this way, before moving on to experimental data.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- Optimization Module and
- either the Acoustics Module, MEMS Module, Multibody Dynamics Module, or Structural Mechanics Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
