You can create the following types of interaction properties:
- Contact
-
A contact interaction property can define tangential behavior (friction and
elastic slip) and normal behavior (hard, soft, or damped contact and
separation). In addition, a contact property can contain information about
damping, thermal conductance, thermal radiation, and heat generation due to
friction. A contact interaction property can be referred to by a general
contact, surface-to-surface contact, or self-contact interaction. For detailed
instructions on defining this type of interaction property, see
Defining a contact interaction property.
- Film
condition
-
A film condition interaction property defines a film coefficient as a
function of temperature and field variables. A film condition interaction
property can be referred to only by a film condition interaction. For detailed
instructions on defining this type of interaction property, see
Defining a film condition interaction property.
- Cavity
radiation
-
A cavity radiation interaction property defines emissivity for a cavity as a
function of temperature and field variables. A cavity radiation interaction
property can be referred to only by a cavity radiation interaction. For
detailed instructions on defining this type of interaction property, see
Defining a cavity radiation interaction property.
- Fluid
cavity
-
A fluid cavity interaction property defines the type of fluid occupying the
cavity and the fluid properties. You can choose either a hydraulic fluid or a
pneumatic fluid. Hydraulic fluids must include a fluid density; and they may
include a fluid bulk modulus, thermal expansion coefficients, and other
temperature-dependent data. Pneumatic fluids must include an ideal gas
molecular weight, and they may include a molar heat capacity (Abaqus/Explicit
only). For detailed instructions on defining this type of interaction property,
see
Defining a fluid cavity interaction property.
- Fluid
exchange
-
A fluid exchange interaction property defines the fluid flow between a
cavity and the environment or from one cavity to another. You can define a
fluid exchange based on bulk viscosity, mass flux, mass rate leakage, volume
flux, or volume rate leakage. For detailed instructions on defining this type
of interaction property, see
Defining a fluid exchange interaction property.
- Fluid
inflator
- A fluid inflator interaction property
defines the mass flow rate and temperature as a function of inflation time
either directly or by entering tank test data. It also defines the mixture of
gases entering the fluid cavity. For detailed instructions on defining this
type of interaction property, see
Defining a fluid inflator interaction property.
- Acoustic impedance
-
An acoustic impedance interaction property defines surface impedance or the
proportionality factors between the pressure and the normal components of
surface displacement and velocity in an acoustic analysis. An acoustic
impedance interaction property can be referred to only by an acoustic impedance
interaction. For detailed instructions on defining this type of interaction
property, see
Defining an acoustic impedance interaction property.
- Incident
wave
-
An incident wave interaction property defines the speed of the incident wave
and other characteristics of the wave loading. An incident wave interaction
property can be referred to only by an incident wave interaction. For detailed
instructions on defining this type of interaction property, see
Defining an incident wave interaction property.
- Actuator/sensor
-
An actuator/sensor interaction property provides the
PROPS, JPROPS,
NPROPS, and
NJPROPS variables that are passed into a
UEL user subroutine used with an actuator/sensor interaction.
For detailed instructions on defining this type of interaction property, see
Defining an actuator/sensor interaction property.
