Name of bonded node set.
Maximum uniaxial normal force, . This value must be nonzero and positive.
Maximum uniaxial shear force, . This value must be nonzero and positive.
Initial bead size, .
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.
