load cases in Abaqus #93

Open franaudo opened 5 years ago

franaudo commented 5 years ago

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

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

*End Step
