Stress-constrained optimization of multiscale structures with parameterized microarchitectures using machine learning
Problem
Designing multiscale structures under stress constraints is difficult because evaluating microstructure material properties and local stress states is computationally costly.
Why it matters
Accurate, efficient stress prediction enables lighter structures that meet safety-critical stress requirements.
What the AI did
Two neural network surrogate models predict homogenized effective properties and local microstructure stresses, embedded in an augmented Lagrangian stress-constrained topology optimisation framework.
Results
not stated in source
Impact
Abstract claims example designs with varied microarchitectures respecting local stress constraints; no metrics given.
