Importing results from an Abaqus/Standard direct cyclic analysis

If the results are imported from a direct cyclic analysis, you can specify the step and iteration number in the restart file for which the results are to be imported. By default, the results written at the end of the analysis are imported.

Input File *IMPORT, STEP=step, ITERATION=iteration Usage:

For models that are defined as assemblies of part instances, the

*IMPORT option must appear within a part instance definition.

Abaqus/CAE In Abaqus/CAE you can import model data and results only from Usage:

models that are defined as assemblies of part instances.

Load module: Create Predefined Field: Step: Initial: choose Other for the Category and Initial State for the Types for Selected Step:

select instances: Step: select Specify: step and Frame: select Specify: iteration

Importing results from an Abaqus/Explicit analysis

If the results are imported from an Abaqus/Explicit analysis, you can specify the step and interval in the state file for which the results are to be imported. By default, the results written at the end of the analysis are imported.

Input File *IMPORT, STEP=step, INTERVAL=interval

Usage:

For models that are defined as assemblies of part instances, the

*IMPORT option must appear within a part instance definition.

Updating the imported configuration

Once the current model configuration of an Abaqus analysis is imported into Abaqus/Explicit or Abaqus/Standard, the analysis can be continued with or without updating the reference configuration to be the imported configuration. If the reference configuration is not updated to be the imported configuration, the displacements and strains are reported as total values relative to the original reference configuration and will, hence, be continuous. If the reference configuration is updated to be the imported configuration, displacements and strains reported in the import analysis are the total values relative to the updated reference configuration. This choice is useful if results need to be displayed relative to the imported configuration, such as may be desirable in springback analysis. The reference configuration cannot be updated if the imported analysis is geometrically linear.

If connector elements are imported, the configuration can be updated provided that the state is not imported.

Input File Use the following option to specify that the reference configuration is

to be updated to the imported configuration: *IMPORT, STEP=step, UPDATE=YES

Usage:

Use the following option to specify that the reference configuration

should not be updated to the imported configuration:

*IMPORT, STEP=step, UPDATE=NO

For models that are defined as assemblies of part instances, the *IMPORT option must appear within a part instance definition.

Importing the material state

You can specify whether or not the associated material state should be imported. If you choose to import the material state, the following are imported:

? ? ? ? ? ?

stresses;

equivalent plastic strains;

back stresses for the kinematic hardening models; user-defined state variables;

damage-related state variables for the concrete damaged plasticity model; damage-related state-variables for traction-separation response with cohesive elements;

? damage-related state variables for ductile metals;

? ?

damage-related state variables for fiber-reinforced composites;

maximum deviatoric strain energy density during deformation history for Mullins effect;

? ?

internal strains and stresses for viscoelastic material models; and

connector state variables such as plastic strains, frictional slip, and damage state.

Thus, the state is imported correctly for further analysis only for the following:

? ? ? ? ? ? ? ? ? ? ? ? ? ?

linear elasticity,

Mises plasticity (including the kinematic hardening models), extended Drucker-Prager plasticity, crushable foam plasticity, Mohr-Coulomb plasticity, critical state (clay) plasticity, cast iron plasticity,

concrete damaged plasticity,

hyperelasticity (including Mullins effect), hyperfoam, viscoelasticity,

traction-separation response with damage for cohesive elements, damage for ductile metals,

damage for fiber-reinforced composites,
