If you want to learn how to analyze elastoplastic behavior in COMSOL Multiphysics®, then tune into this webinar.

Most materials behave elastically under a small applied stress, meaning that the object returns to its original shape when the stress is removed. When the stress passes a certain threshold, however, plastic strains result in permanent deformation. Plasticity is desired for some processes, such as metal forming. On the other hand, during the service life of many structures, such as pressure vessels, we are interested in avoiding irreversible deformations or limiting the volume fraction of material that has exceeded the elastic limit.

In this presentation, we will discuss several built-in yield criteria in COMSOL Multiphysics® that can be used to specify the onset of plasticity and hardening functions for characterizing the response after the initial yielding. You can also specify your own yield criteria and hardening functions.

In a live software demonstration, you will learn how to simulate elastoplasticity using built-in and user-defined plasticity models. You will also see how to use multiphysics couplings to model, for instance, the effect of temperature on plasticity and heat generation from mechanical dissipation. You can interact with the presenter by asking questions during the webinar.
