Constitutive Law
This MPM material is a programmed-burn model for simulating certain detonation scenarios.
Material Properties
The properties for a Tait liquid are:
| Property | Description | Units | Default |
|---|---|---|---|
| time0 | Detonation start time | time units | 0 |
| StartX | Detonation starting x position | length units | 0 |
| StartY | Detonation starting y position | length units | 0 |
| StartZ | Detonation starting z position | length units | 0 |
| NormX | Planar wave normal in x direction | length units | 0 |
| NormY | Planar wave normal in y direction | length units | 0 |
| NormZ | Planar wave normal in z direction | length units | 0 |
| Dv | Detonation velocity | alt velocity units | none |
| Dw | Detonation front width. The extent of reaction of these particle goes from 0 to 1 over a length equal to this width. The time for a given partile to burn once it starts is thus Dw/Dv. | length units | none |
| DeleteDist | Particle deletion distance. If a particle is greater than this distance from the starting location (for spherical wave) or starting plane (for planar wave), the particle is deleted from the simulation. | length units | none |
| nm | none | none | |
| Ajwl | pressure units | none | |
| Bjwl | pressure units | none | |
| Cjwl | pressure units | none | |
| R1 | none | none | |
| R2 | none | none | |
| Omega | none | none |
