Buckling Analysis
Calculate the buckling load factor from a nonlinear load-displacement analysis
Inputs
| Name | ID | Description | Type |
|---|---|---|---|
| Goals | PGoals | Permanent goals e.g. bar, rod and support goals as FLATTENED list | Generic Data |
| Load | LGoals | K2Structural load goals | Generic Data |
| LFStart | LFstart | The start load factor | Number |
| LFStep | LFstep | The load factor step size | Number |
| Angle | alfa | Specify the allowed angle deviation between the tangent to the load-displacement curve and vertical in [degrees] | Number |
| Displ | dMax | Specify the maximum allowed displacement for a vertex in [m] | Number |
| Threshold | thres | The total kinetic energy threshold to define equilibrium | Number |
| IterationCount | iter | Specify the maximum number of equilibrium iterations for each load increment | Integer |
| OutputAll? | opt | Output option. If true, displacements and goal results are output for each load increment. If false, only for the last two | Boolean |
Outputs
| Name | ID | Description | Type |
|---|---|---|---|
| BucklingLoadFactor | BLF | The buckling load factor [-] | Number |
| LoadFactors | LF | Load factor for each iteration | Number |
| DisplacementRMS | dRMS | The displacements as a RMS value in [m] for each iteration | Number |
| VertexPositions | V | The vertex positions for each iteration | Point |
| GoalOutput | O | The output from the goals for each iteration. The data structure is identical to the PGoals input | Generic Data |
