Large Deformation & Nonlinear Material Behavior

Rigid body dynamics if often used to assess the kinematics and dynamics of mechanical systems. However, increasing demand for material reduction and faster operational speeds may require simulation fidelity beyond the reach of rigid body assumptions. In these cases, ANSYS Rigid Dynamic models can be converted to a fully or partially flexible model in a few mouse clicks without having to transfer data to and from third-party software components. Flexibility can be modeled in the linear range. Alternately, geometric and material nonlinearities can be enabled to capture large deformation, stress stiffening, and plasticity, among other solid continuum phenomena.
