Flexible-Body Motion with Nonlinear Material Models
Mechanical Event Simulation (MES) combines large-scale motion and stress analysis including flexible-body motion with nonlinear material models to account for the bending, twisting, stretching, squashing and inertial effects of an FEA model. In addition to rigid-body motion and linear flexible-body motion, MES using nonlinear material models can simulate geometric and material nonlinearities (such as large deformation beyond the material yield point). The combination of motion and stress analysis considering full inertial effects enables engineers to see motion and its results, such as impact, buckling and permanent deformation. To set up flexible-body motion with nonlinear material models, select a nonlinear material model and supply the needed data. For example, if considering a part comprised of a material with a yield stress, use a material model capable of simulating plasticity. Thus, you will need material properties for both the linear range and for beyond yield, when the strength of the part has been reduced. It should be noted that the former type of material properties coincide with those used by linear static stress analysis. Since the entire MES is displayed on the screen, it will be apparent if yielding or failure occur. The following nonlinear material models are available for models with flexible-body motion:
