Project
Experimentally Quantified Microstructure-Property Relations for Modeling



Description:

To quantify microstructure-property relations using various microscopy techniques and experimental results. From these results material characteristics can be determined using a plasticity-damage model. These characteristics can then be implemented into various finite element analysis codes and optimization programs to develop improved design parameters.

Microstructure-Property Equations


Scientific Merit
The determination of cause-effect relationships of the material microstructure-properties is little known for accurate simulation predictions.

Microscopy Experiments


Mesoscale Nickel Analysis vs. Experiments


Mechanical Experiments


Finite Element Analysis Implementation
Microstructure-property relationships are used in Finite Element Analysis codes to provide better material damage predictions.


Status
• Dodge Neon body-in-white component experiments have begun
• Material characteristics for A356 aluminum and AM60B magnesium are almost complete

Future Work
• Focused experiments on specific parts for various crash types (frontal, rear, side impact)
• Alcoa 6022 aluminum alloy experiments to determine material microstructure-property relations
