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 |
|---|---|---|---|
| K | Zero-pressure, bulk modulus | pressure units | none |
| viscosity | Liquid viscosity at one shear rate (note that legacy units are cP = 1 mPa-sec) | viscosity units | none |
| logshearrate | log of shear rate corresponding to a viscosity | 1/(time units | none |
| alpha | Linear thermal expansion coefficient (β0 = 3α) | ppm/K | 0 |
| InitialPressure | You can set initial pressure to a user defined function of position that evaluates to a pressure in pressure units. When liquids are modeled in gravity, the function can set to ρgh, where h is height of liquid above the position (x, y, z). | pressure units | none |
| (other) | Properties common to all materials | varies | varies |
History Variables
None
