This study evaluates the consequences of modelling a weld-generated Heat Affected Zone when optimizing lightweight steel structures for crashworthiness. A case study on the resistance of an X-core sandwich panel is presented using a Particle Swarm Optimization-algorithm to search the design space for optimal solutions. Structures are developed by procedures including-and excluding a HAZ effect and later compared. The developed structures show distinct differences in terms of geometry, energy absorbed per unit mass, failure mode and sensitivity to HAZ material properties. Highlighting the importance of a proper set up for structural optimization, these findings question the validity of omitting weld effects when optimizing for crashworthiness.
