A design optimization of high-strength steel tailor welded thin-walled structures under crashworthiness is developed.
- class="label">•
Surrogate models are constructed to approximate the crashworthiness responses of these TWB structures.
- class="label">•
Global sensitivity analysis is used to investigate the influence of design variables and parameters.
- class="label">•
Reliability based design optimization is carried out by taking into account the uncertainties in TWB configuration.
