block.subcontact.state
Syntax
- i = block.subcontact.state(bscp)
- block.subcontact.state(bscp) = i
Get/set the subcontact state indicator.
The subcontact failure state is represented by a variable with 64 bits. Each bit refers to a potential state. Different joint constitutive models will have different potential states (see Constitutive Models in 3DEC). The potential states for the Mohr-Coulomb model are shown in the table below.
| MC Failure States | Value | Label |
|---|---|---|
| Failure in shear now | 1 | slip-n |
| Failure in tension now | 2 | tension-n |
| Failure in shear in the past | 4 | slip-p |
| Failure in tension in the past | 8 | tension-p |
Combinations of states are possible by turning on different bits. For example, a subcontact that failed in tension in the past and is shearing now would have a state value of 8 + 1 = 9. A value of 0 indicates no failure (elastic).
