Mesh-independent fasteners

The mesh-independent fastener capability:

  • is a convenient method to define a point-to-point connection between two or more surfaces such as a spot weld or rivet connection;

  • uses spatial coordinates of fastener locations to define point-to-point connections independent of underlying meshes;

  • combines either connector elements or BEAMMPCs with distributing coupling constraints to provide a connection that can be located anywhere between two or more surfaces regardless of the mesh refinement or location of nodes on each surface;

  • can be used to connect both deformable and rigid element-based surfaces;

  • can model either rigid, elastic, or inelastic connections with failure by using the generality of connector behavior definitions; and

  • is available only in three dimensions.
