How to Implement Elastoplasticity in a Model Using External Materials
Sometimes the mechanical behavior of a material is not readily expressed in terms of a built-in model. In these cases, you can use external materials. Learn how with an elastoplasticity example.
Simulating Powder Compaction with Porous Plasticity Models
Powder compaction is an important and popular technique in many manufacturing industries. You can use porous plasticity models to analyze and improve the powder compaction process.
Modeling Fatigue Failure in Elastoplastic Materials
Imagine bending a metallic paper clip back and forth until, after a few repetitions, it breaks entirely. This is one example of fatigue failure, the most common type of structural collapse. In more severe cases, such failure can lead to collapse or malfunction in structures like car exhaust pipes and aircraft jet engines. To better understand and predict fatigue failure in elastoplastic materials, we can use the COMSOL Multiphysics® software to accurately model both the materials and the fatigue process.
