*CONTACT_SINGLE_EDGE Corrugated Sheet Contacts Edges LS-DYNA Manual Section: *CONTACT_SINGLE_EDGE Additional Sections: *CONTACT_FORCE_TRANSDUCER_PENALTY Example: Corrugated Sheet Contacts Edges Filename: contact.edge.k Description: A corrugated plate strikes a flat plate from opposite directions. Input: The model consists of 135 elastic plastic Belytschko-Tsay shell elements. The interaction of the two structures is to edge contact (*C ONTACT_SINGLE_EDGE). A contact force transducer is defined to monitor the forces of the contact in the ascii file rcforc. The nodes on the upper corrugated plate have an initial velocity of 10 meters/second. Results: A contour plot of the effective-stress and a plot of the forces from the ascii file rcforc illustrate that the plates are in contact. Reference: Stillman, D. W.
