Sažetak
In this work structure is modeled as a nonlinear dynamical system. Usually, structures are modeled using FEM and material model is included into the continuum model while discrete material models need some additional transformation to be included into FEM [1]. Approach adopted here formulates structure model as a system of nonlinear differential algebraic equations with the material model integrated into it. As a result, the material model is directly coupled with structure and there is a direct link between structure behavior and its parameters. Also, loading is a part of structure description i.e. it is incorporated into differential equations describing the system and one can determine the sensitivity to various material or loading parameters. This particular aspect is missing from the FEM model describing the nonlinear dynamical system.
