Large Deformation Analysis of a Beam
Application ID: 204
This example studies the deflection of a cantilever beam undergoing very large deflections. The beam is modeled using both the Solid Mechanics interface and the Beam interface. The results are compared with each other and with a benchmark solution from NAFEMS. In addition, a linear buckling analysis is performed and the critical load obtained from this study is compared with Euler's critical load.
The model comes from Section 5.2 of NAFEMS Background to Finite Element Analysis of Geometric Non-linearity Benchmarks.
This model example illustrates applications of this type that would nominally be built using the following products:Structural Mechanics Module
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:
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.
