Thin Layer Interfaces
This model demonstrates alternative implementations used for describing a thin layer and the impact of the choice on the continuity of the displacement and stress fields. It is shown how a perfect interface can be obtained by asymptotically changing the material parameters. En savoir plus
Uniaxial Stretching of a Rectangular Sheet
This example demonstrates the wrinkling of a thin rectangular sheet stretched uniaxially. First, a static analysis is performed to determine the region of negative principal stresses without wrinkling. Next, a prestressed buckling analysis is carried out to find out the linearized ...

Tire Inflation
This model showcases how to use fibers in thin layers to model thin anisotropic composites embedded in a solid without explicitly drawing either the layer of material or the reinforcing fibers. Here, it is used to model steel cords in tire belts that are used to provide structural ... En savoir plus
Inflation of a Square Hyperelastic Airbag
A square airbag made of a hyperelastic, compressible neo-Hookean material is inflated using pressurized air. Compressive stresses trigger wrinkling in some regions of the thin airbag. In this example, the wrinkling behavior is modeled using tension field theory, which gives a correct ... En savoir plus
Primary Creep Under Nonconstant Load
In this model example, you will study the creep behavior of material under non-constant loading. You will model the primary creep using a Norton–Bailey law and study the difference between the time hardening and the strain hardening methods available in COMSOL Multiphysics. The model is ...

Powder Compaction of a Rotational Flanged Component
The powder compaction process is becoming common in the manufacturing industry, thanks to its potential to produce components of complex shape and high strength. In this example, the compaction of iron powder to form an axisymmetric rotational flanged component is analyzed with capped ... En savoir plus
Pressurized Orthotropic Container — Shell Version
A thin-walled container made of rolled steel is subjected to an internal overpressure. As an effect of the manufacturing method, the out-of- plane direction has a higher yield stress than the other two directions. Hill’s orthotropic plasticity is used to model the difference in yield ... En savoir plus
Submodeling with Plasticity
In this tutorial model, it is demonstrated how to incorporate a localized nonlinearity in a submodel. In this case, an initial elastic analysis reveals that a small region of a structure has stresses above the yield limit. To improve the results, an elastoplastic material model is added ...
