*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.

This page discusses:

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, Ffn. This value must be nonzero and positive.

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

  4. Initial bead size, db.

  5. Time to failure, Tf. If Tf is nonzero, the breakage displacements ufn and ufs 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, Ffn. This value must be nonzero and positive.

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

  4. Initial bead size, db.

  5. Blank space.

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

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

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