Yaris Dynamic Roof Crush

One of the tests used in occupant safety analysis is a roof crush test. It is used to evaluate how a car will deform during a rollover accident. A safer car does not deform as much providing the occupant a larger survival space during this kind of accident. In this test, a plate shaped impactor is pushed down on one side of the roof at constant (slow, quasi-static) speed. This load case challenges the solver because of large deformations, complex contact situations as well as local buckling. This model was computed successfully with the LS-DYNA R9.0.1 MPP implicit solver including dynamic effects. Last but not least, we want to acknowledge the CCSA for the baseline model.
