Tensile Test with Strain Rate Dependent Plasticity
Application ID: 75431
In this example, a tensile test is simulated at four different strain rates. The Johnson-Cook hardening law is used to model the strain rate dependency of the plastic hardening.
The temperature distribution and thermal expansion caused by the heating generated by the plastic deformation are also computed. In a separate study, the influence of including a temperature dependency in the Johnson-Cook model is examined.
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
- Nonlinear Structural Materials Module and
- either the MEMS 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.
