load cases in Abaqus

[franaudo]

In Abaqus it is possible to define load cases within a static perturbation, direct-solution steady-state dynamic, and SIM-based steady-state dynamic analyses. Load case definitions do not propagate to subsequent steps.

The keyword for the input file is:

*LOAD CASE, NAME=name
*END LOAD CASE

Typical step structure for load cases:

** STEP: Step-Name
**
*Step, name=Step-Name, nlgeom=NO, perturbation

Load case 1: only BC and load-2 with scale factor 1.5:

*Load Case, name=LoadCase-1
** Name: BC-1 Type: Symmetry/Antisymmetry/Encastre Scale factor: 1
*Boundary, op=NEW
Set-2, ENCASTRE
** Name: Load-2 Type: Concentrated force Scale factor: 1.5
*Cload
Set-6, 2, -1.5
*End Load Case

Load case 2: only BC and load-3 with scale factor 1:

*Load Case, name=LoadCase-2
** Name: BC-1 Type: Symmetry/Antisymmetry/Encastre Scale factor: 1
*Boundary, op=NEW
Set-2, ENCASTRE
** Name: Load-3 Type: Concentrated force Scale factor: 1
*Cload
Set-7, 2, -1.
*End Load Case

Load case 1: BC + load-2 + load-3 with different scale factors:

*Load Case, name=LoadCase-3
** Name: BC-1 Type: Symmetry/Antisymmetry/Encastre Scale factor: 1
*Boundary, op=NEW
Set-2, ENCASTRE
** Name: Load-2 Type: Concentrated force Scale factor: 1.7
*Cload
Set-6, 2, -1.7
** Name: Load-3 Type: Concentrated force Scale factor: 1.2
*Cload
Set-7, 2, -1.2
*End Load Case
