ST7-1.20.10.8 Troubleshooting Nonlinear Static Models
Solutions to nonlinear FEA problems are approximate due to the iterative nature of the algorithms used to solve the problems. Before proceeding, review ST7-1.10.10.3 General Model Troubleshooting to ensure that the model is basically sound.
In this example, a fictitious welded assembly, which is between two confining walls, is forced downwards by an eccentric load until lateral buckling occurs and contact is formed between the buckled member and the adjacent walls.
The base of the buckling...
