Parameter definition
| Variable | Description |
|---|---|
| mfid | Merge failure command ID |
| $T_{fail}$ | Tensile failure force |
| $S_{fail}$ | Shear failure force |
| $n_T$ | Tensile failure exponent |
| $n_S$ | Shear failure exponent |
Description
This command specifies failure of a blind hole bolt MERGE interface. Failure is initiated when:
$\left( \frac{T}{T_{fail}} \right)^{n_T} + \left( \frac{S}{S_{fail}} \right)^{n_S} \geq 1$
where $T$ and $S$ are the total tensile and shear forces in the bolt-hole interface.
The command can also be used to predict failure of nut-bolt MERGE interfaces, but then only the tensile failure criterion will be active.
