... the polymers experience large amounts of deformation. The mesh of the WIAMan ATD neck model consists of 207,000 elements, and 195,000 nodes. All of the elements are solids and are comprised of 72% hex elements and 28% tetrahedral elements (around the face and skull). Material fits were trained...
