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 description here *Static

** OUTPUT REQUESTS ** **

** LOAD CASES **

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
