Integrated Computational Materials Engineering Approach to Development of a Lightweight Third Generation Advanced High-Strength Steel (3GAHSS) Vehicle Body Structure 2018-01-1026

This paper covers an application of integrated computational materials engineering (ICME) for third generation advanced high-strength steel (3GAHSS) grades to vehicle light weight body structure development. Following a brief overview of the ICME project, design optimization of a vehicle body structure using a multi-scale ICME material model is discussed. Design optimization steps and results are presented. Results show a 30% mass reduction potential of a mid-size sedan body side structure with the use of 3GAHSS.
