STABILIZE

Include this parameter to use automatic stabilization if the proble m is expected to be unstable due

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

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

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

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

is 2 × 10−4. If the FACTORparamet er is used, any value of the dissipated energy fraction will be

overridden by the damping factor.

Data line for a transient, quasi-static analysis:

First (and only) line:

1. Suggestedinitial time increment. Thisvalue should be reasonably correct (in agreement with

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

incrementation is being used.

2. Time period of the step.

3. Minimum time increment allowed. If ABAQUS/Standard ﬁnds it needs a smaller time

increment than thisvalue, the analysis is terminated. Ifthis entry is zero, a default value of the

smaller of the suggested initial time increment or 10−5 tim es the total time period is assumed.

4. Maximumtim e increment allowed. Only u sed for automatic time incrementation. Ifthis value

is not speciﬁed, no upper limit is imposed.
