*MERGE_FAILURE_FORCE
mfid, $T_{fail}$, $S_{fail}$

Parameter definition

VariableDescription
mfid Merge failure command ID
$T_{fail}$ Tensile failure force
$S_{fail}$ Shear failure force

Description

Specifies failure of a merged interface MERGE. Failure is initiated when:

$\left( \frac{T}{T_{fail}} \right)^2 + \left( \frac{S}{S_{fail}} \right)^2 \geq 1$

where $T$ and $S$ is the total tensile force and shear force between the merged interfaces, respectively. Note that compressive forces will not lead to failure.
