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 might include a fluid bulk
modulus, thermal expansion coefficients, and other temperature-dependent data. Pneumatic
fluids must include an ideal gas molecular weight, and they might 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.
- Wear
-
A wear interaction property defines the contact wear properties based on Archard's wear
rate model (see Contact Wear). For detailed instructions on
defining this type of interaction property, see Defining a wear interaction property.
