Required, mutually exclusive parameters- ACCELERATION AMPLITUDE
Set this parameter equal to the name of the amplitude curve defining the
fluid particle acceleration time history at the standoff point (Amplitude Curves).
This amplitude curve will be used to compute the fluid traction
only: a solid surface requiring a pressure load
cannot be specified on the data line of an
INCIDENT WAVE INTERACTION option if the ACCELERATION AMPLITUDE parameter is used.
This parameter is valid only for transient planar incident waves using the
INCIDENT WAVE INTERACTION PROPERTY, TYPE=PLANE option. Reflected loads, using the
INCIDENT WAVE REFLECTION option, are not permitted in this case.
- CONWEP
This parameter applies only to
Abaqus/Explicit
analyses.
Include this parameter to define an incident wave using the
CONWEP CHARGE PROPERTY option. This parameter is valid only for blast waves using
the
INCIDENT WAVE INTERACTION PROPERTY, TYPE=AIR BLAST or TYPE=SURFACE BLAST option.
- PRESSURE AMPLITUDE
Set this parameter equal to the name of the amplitude curve defining the
fluid pressure time history at the standoff point (Amplitude Curves).
The corresponding fluid traction, if required, will be computed from the
pressure amplitude reference.
- UNDEX
Include this parameter to define a spherical incident wave using the
UNDEX CHARGE PROPERTY option. This parameter is valid only for spherical
incident waves using the
INCIDENT WAVE INTERACTION PROPERTY, TYPE=SPHERE option.
Data line to define an incident wave when the CONWEP parameter is omitted- First (and only) line
Surface name.
The node number or set name of the source node.
The node number or set name of the standoff node.
Reference magnitude.
Data line to define an incident wave when the CONWEP parameter is included- First (and only) line
Surface name.
The node number or set name of the source node.
Blank field.
Time of detonation given in total time. See
Conventions
for a discussion of the total time measure.
Magnitude scale factor. The default is 1.0.
