STABILIZE

Include this parameter to use automatic stabilization if the problem is e xpected to be u nstable due

to local instabilities. Set this parameter equal to the dissipated energy fraction of the automatic

damping algorithm (see “Solving nonlinear problems,” Section 7.1.1 of the ABAQUS Analysis

User’s Manual). If this parameter is omitted, the stabilization algorithm is not acti v ated. If this

parameter is included without a speciﬁed value, the default value of the dissipated energy fraction

is 2 × 10

−4

. If the FACTOR par ameter is used, any v alue of the dissipated energy fr action will be

overridden by the damping factor.

Data line for a transient, quasi-static analysis:

First (and only) line:

1. Suggested initial time increment. This value should be reasonably correct (in agreem ent with

the strain change allowed with the CETOL parameter) but may be reduced if automatic time

incrementation is being used.

2. Time period of the step.

3. Minim um tim e increment allowed. If ABAQUS/Standard ﬁnds it needs a smaller tim e

increment than this value, the analysis is terminated. If this entry is zero, a default value of the

smaller of the suggested initial time increment or 10

−5

times the total time period is assumed.

4. Maximum time increment allowed. Only used for automatic time incrementation. If this value

is not speciﬁed, no upper limit is im posed.
