Absolute Nodal Coordinate Formulation in a Pre-Stressed Large-Displacements Dynamical System

, 2017
The design process for dynamical models has to consider all the properties of a mechanical system that have an effect on its dynamical response. In multi-body dynamics, flexible bodies are frequently modeled as rigid, resulting in non-valid modeling of ...
