## Objective
|
|
|
|
|
|
|
|
|
|
|
|
Optimize a sandwich I-beam with lightening holes: minimize mass while meeting stiffness and strength constraints.

|
|
|
|
|
|
| Mass | ~974 kg | Minimize |

|
| Half-core thickness | 10–40 mm | Continuous |

|
|
|
|
|
| Hole count | 5–15 | Integer |
|

## Approach
|
|
|
|
|
|
|
|
|
|
|
|
Two-phase optimization:
|
|
|
|
|
|
1. **DoE** (LHS, 40–50 trials) — map the landscape
|
|
|
|
|
|
2. **TPE** (Bayesian, 60–100 trials) — converge to optimum
|
|
|
|
|
|
|
|
|
|
|
|
Total budget: ~100–150 NX evaluations, est. 2–5 hours compute.
