Soft Bond Model Methods

The methods of the Soft-Bond Model model are shown below for reference. More detailed information regarding these methods is presented here.

softbond
area

Set the user_area property, fixing the contact area, from the current sb_area.

deformability keyword ...

Set the deformability.

emod f

Specify the effective Young’s modulus.

kratio f

Normal-to-shear stiffness ratio.

bond keyword ...

Activate the bond.

gap f1 <f2 >

Bond contacts with the gap interval specified. If only one value is specified this is the upper bound of the interval. If two values are specified they correspond to the lower and upper bounds of the interval, respectively. By default the interval is \((-\infty,0]\).

soft f

Set the softening factor.

cut f

Set the softening tensile strength factor.

unbond <keyword>

Deactivate the bond.

gap f1 <f2 >

Unbond contacts with the gap interval specified. If only one value is specified this is the upper bound of the interval. If two values are specified they correspond to the lower and upper bounds of the interval, respectively. By default the interval is \((-\infty,0]\).
