Material / Joint Performance
The projects that fall under this thrust area have an emphasis on material / joint performance.
Our Research Efforts on Material / Joint Performance
Focus is on the understanding and optimization of welded/printed materials performance when exposed to industry service environments. Assess using a multitude of variables including: material composition, welding/printing process and techniques, and service conditions. Dynamic material performance includes examination of the effects of strain, fatigue and corrosion. Includes validation and development of models based on experimental results. Goal is to optimize materials, welding, and printing solutions, as well as the code requirements governing industry.
