Instability of a Space Arc Frame

This model illustrates the instability of a space arc frame under concentrated vertical loading. A small lateral load is applied to break the symmetry of the structure. Members in the frame are modeled using geometrically nonlinear beam elements. The results are compared with available literature data.

External Material Examples, Structural Mechanics

A new way to specify user-defined material models is included in COMSOL Multiphysics version 5.2. For structural mechanics, you have the possibility to either completely define the material model in a domain, or to add an inelastic strain contribution to an elastic material. The external material functions are coded in C, and compiled into a shared library. By programming a wrapper function in ...

Generalized Kelvin Viscoelastic Material - new

The behavior of viscoelastic materials can be represented by conceptual models composed of elastic and viscous elements connected in series or in parallel. The rheology of the generalized Kelvin model (also called generalized Kelvin-Voigt model) consists of an elastic spring to represent the instantaneous stiffness plus n Kelvin-Voigt branches connected in series. This example shows how to ...
