M10 mastery test

Assessment of NLGEOM, substeps, plasticity, and interpreting convergence.

Exit checklist

  • Linear baseline with equilibrium < 0.5%.
  • NLGEOM ON with n_sets = 10.
  • geom_dev_ratio ≥ 0.05%.
  • Plasticity with plastic_dev_ratio ≥ 5%.
  • Challenge with F = −12000 N documented.
  • study_passes=1 in a clean run.

Technical traceability

Commands: NLGEOM, TB,BISO, TBDATA, NSUBST, NEQIT, KBC, OUTRES, SET, *GET. References: Structural Analysis Guide; Material Reference. Inherited from: M07 (KEYOPT(2)=3, equilibrium). Next: M11 contact.

Mastery assessment

Show that you can do it without hints

You need at least 80% and every critical check correct. You can retry without a limit; each attempt gives you a focused review path.

6 checks

Competency

Control geometric and material nonlinearity with verifiable substeps.

Expected evidence

NLGEOM solved with n_converged=n_substeps, equilibrium <0.5% and documented deviation.

2.In a static ramp with KBC,0, what does TIME=0.5 represent? Critical
3.n_sets=1 after NSUBST=10 and progressive ramp. Most likely cause? Critical
4.Enter theoretical |uy_ref| (m) for L=0.5 m, h=0.04 m, b=0.05 m, F=−10000 N, E=210 GPa. Critical
m
5.How many converged substeps does the contract require for the geometric case (n_substeps=10)? Critical
substeps
6.The elastoplastic case shows a greater deflection than the elastic geometric case. Correct interpretation?
