This FEA capability allows us to perform full 3D impact analysis with multiple colliding bodies, including automobile collisions, crane tip-overs, ladder and chair accidents, and more. Rigid and deformable body motion can be analyzed, as well as models that contain both. (For example, in an automobile collision, the front of the automobile that deforms is modeled with deformable elements, and the rear of the automobile can be modeled as a rigid body to reduce the time necessary to run the analysis without losing significant information or accuracy.) These complex models can include human (dummy) components, as well as seat belts and airbags, to determine the dynamic response of a person in the analysis.
Failure or damage, such as tearing, fracture, and buckling, can be computed as a function of time for any components being modeled. This method can be applied to components made of ceramics, steel, plastic, concrete, soil, or any other material. |
