"Eroding contact types are recommended whenever solid elements involved in the contact definition are subject to erosion (element deletion) due to material failure criteria. These eroding contacts contain logic which allow the contact surface to be updated as exterior elements are deleted. See more One-way contact types allow for compression loads to be transferred between the slave nodes and the master segments. Tangential loads are also transmitted if relative … See more In tied contact types, the slave nodes are constrained to move with the master surface. At the beginning of the simulation, the nearest master segment for each slave node is located … See more This contact works essentially the same way as the corresponding one-way treatments described above, except that the subroutines which check the slaves nodes for … See more These contact types are the most widely used contact options in LS-DYNA, especially for crashworthiness applications.
