INITIAL CONDITIONS
to read for any node is based on the maximum number of field variable va lues for all the nodes in
the model. These trailing initial values will be zero and will not be used in the analysis.
Repeat this set of data lines as often as necessary to define initial temperatures at various nodes or node
sets.
No data lines are required for TYPE=FIELD, VARIABLE=n,FILE=file,STEP=step,INC=inc.
Data lines for TYPE=FLUID PRESSURE:
First line:
1. Node set or node number of fluid cavity reference node.
2. Fluid pressure.
Repeat this data line as often as necessary to define initial fluid pressure for various fluid-filled cavities.
Data lines to prescribe initial equivalent plastic strain or backstresses using TYPE=HARDENING
if the REBAR, SECTION POINTS, and USER parameters are omitted:
First line:
1. Element number or element set label.
2. Initial equivalent plastic strain,
.
3. First value of the initial backstress,
. (Only relevant for the kinemati c hardening models.)
4. Second value of the initial backst ress,
. (Only relevant for the kinem atichardening models.)
5. Etc., up to six backstress components. (Only relevant for the kinematic hardening models.)
Give the backstress components as defined for this element type in Part V I, “Elements,” of the
ABAQUS Analysis User’s Manual. Values given on the data lines are applied uniformly over the
element. In any elem ent for which an
*
ORIENTATION option applies, backstresses m ust be given
in the local system (“Orientations,” Section 2.2.5 of the ABAQUS Analysis User ’s Manual).
Repeat this data line as often as neces sary to define the hardening parameters for various elements or
element sets.
Data lines to prescribe initial volumetric compacting plastic strain for the c rushable foam model
using TYPE=HARDENING:
First line:
1. Element number or element set label.
2. Initial volumetric compacting plastic strain,
.
Repeat this d ata line as often as necessary to define the initial volumetric compacting plastic strain for
various elements or element sets.
