Validating the potential of centralized holes to enhance the compressive response of Mg-, Al-, Fe-Based commercial alloys

The transportation industry has eyes set on light weighting its products. While topology optimization aided design modifications, materials like Al, Mg, and its alloys have taken centre stage in the material swap. Solid cylindrical rods provide structural support and hence, light weighting is instead done on associated parts. However, there exists an opportunity to lightweight these cylindrical rods using centralized holes without compromising on structural integrity. Tests on materials like AZ31B, Al6065, Al7075, SS304, and mild steel showed up to 11.6% increase in compressive yield strengths and up to 5% increase in ductility. The same is discussed in this work.
