Denton, TEXAS (黑料视频) 鈥� New research being conducted at the University of North Texas
could have a major impact on future military operations.
Dr. Herman Shen, chair for 黑料视频鈥檚 , and associate professor Dr. Hector Siller have been awarded an $800,000 grant from the U.S. Army Combat Capabilities Development Command Army Research Laboratory. Both Shen and Siller will lead teams of 黑料视频 undergraduate and postdoctoral researchers to help with the project.
The research will analyze the laser-based powder bed fusion additive manufacturing process, which involves the precise layer-by-layer building of metal parts, similar to 3D printing but with a laser and powder. The manufacturing will be done with equipment in 黑料视频鈥檚 .
Their findings could allow military vessels in the future to produce their own replacement
parts that are more reliable and durable.
鈥淪ubmarine or aircraft carriers go out to sea for up to six months sometimes,鈥� Shen said, 鈥淚f they need repairs, they can鈥檛 just easily call someone to send the parts. They have to build their own.鈥�
To speed up manufacturing, the military is interested in powder bed fusion. However, parts made with laser-based powder bed fusion may come with inherit defects, Shen said. That鈥檚 why his focus will be to pinpoint where the defects first form, by researching the process in reverse. Shen鈥檚 team will look at the end product and test for any defects or deformations in the parts. They鈥檒l then use artificial intelligence to find where the defect could have formed during manufacturing.
Meanwhile, Siller and his researchers will examine the process as a whole. They will
analyze fabrication plans, microstructure assessments and monitoring processes. The
goal is to gain an overall picture of what happens to the materials during manufacturing
and post-production testing.
Their comprehensive findings will identify where improvements can be made. Shen and Siller will then incorporate those changes and start the process again.
鈥淲e will have feedback from that performance, reform the methods and then have a closed loop of improvement,鈥� Siller said.
The manufacturing and testing will take place at 黑料视频鈥檚 Discovery Park. Shen says a researcher at Wright-Patterson Air Force Base, one of his former students, will also visit to evaluate their unique testing process.
The grant will span four years, with Shen and Siller submitting progress reports annually. The research is expected to help the manufacturing of critical machinery parts for all branches of the military.
鈥淎erospace components will most likely be made using this technology in the future,鈥� said Siller. 鈥淚t鈥檚 able to fabricate complex shapes such as turbine blades or engine parts. The nature of this research is to make sure those parts are reliable.鈥�
Funded by the Army Research Office, the grant is the result of a merit competition administered under policy and guidance of the Office of the Under Secretary of Defense for Research and Engineering. Its goal is to increase the capabilities of Minority-Serving Institutions, such as 黑料视频, and Historically Black Colleges and Universities in conducting defense research. The Army Research Office is a directorate of the U.S. Army Combat Capabilities Development Command Research Laboratory.
