Pipe-to-pipe impact analysis
In studies of crashworthiness impact and penetration it is not unusual for an analysis to involve 50000 elements and require 20 or more hours on the latest supercomputers, even though the meshes are in fact quite coarse compared to the resolution which would be needed to accurately capture the deformation modes. Parallel supercomputing offers the promise of faster solution to such large problems thereby increasing the analytic model resolution and broadening the scope of design options. As the boxed being collapses against the rigid barrier during impact, additional contacting surfaces are created. The algorythm must effectively detect and treat these new interactions zones to prevent elements from passing through one another. Adaptive finite elements can be used to strategically capture the interaction region between two impacting bodies. Thus the computational power is focused on those parts of the mesh that undergo the most severe deformation.
