*BOND
Define bonds and bonding properties.

This option is used to define breakable bonds that initially tie two contact boundaries to each other. This option must be used in conjunction with the *SURFACE INTERACTION option.

There are no parameters associated with this option.

Data lines to define spot welds with the time to failure model: 

First line:

  1. Name of bonded node set.

  2. Maximum uniaxial normal force, . This value must be nonzero and positive.

  3. Maximum uniaxial shear force, . This value must be nonzero and positive.

  4. Initial bead size, .

  5. Time to failure, . If is nonzero, the breakage displacements and must be left blank.

Repeat this data line as often as necessary to define spot welds using the time to failure model.

Data lines to define spot welds with the damaged model: 

First line:

  1. Name of bonded node set.

  2. Maximum uniaxial normal force, . This value must be nonzero and positive.

  3. Maximum uniaxial shear force, . This value must be nonzero and positive.

  4. Initial bead size, .

  5. Blank space.

  6. Normal breakage displacement, . If is nonzero, the time to failure must be left blank.

  7. Shear breakage displacement, (default value is ). If is nonzero, the time to failure must be left blank.

Repeat this data line as often as necessary to define spot welds using the damaged model.
