Development of a Lightweight Third-Generation Advanced High-Strength Steel (3GAHSS) Vehicle Body Structure

Abstract

<div class="section abstract"><div class="htmlview paragraph">This article covers an application of third-generation advanced high-strength steel (3GAHSS) grades to vehicle lightweight body structure development. Design optimization of a vehicle body structure using a multi-scale material model is discussed. The steps in the design optimization and results are presented. Results show a 30% mass reduction potential over a baseline mid-size sedan body side structure with the use of 3GAHSS.</div></div>
