ME grad student invited to Australia
Cumali Semetay, a Ph.D. candidate in mechanical engineering, was invited recently to Monash University in Melbourne, Australia, to give a series of talks on welding simulation.
Semetay discussed work he is doing with his adviser, Herman Nied, professor and chair of mechanical engineering and mechanics, in Laser Engineered Net Shaping (LENS) simulation using Sysweld finite-element software.
The two-week trip came about as a result of an e-mail sent to Nied from a graduate student at Monash who wanted to learn more about Lehigh's work in welding simulation experience.
Nied forwarded the e-mail to Semetay, who exchanged several more e-mails with Monash students before he was invited to make the trip.
Nied and his students have developed codes to predict and control the fracture behavior of welded stainless steel, which warps during welding more than regular steel does. Their work is part of a multidisciplinary effort at Lehigh's ATLSS (Advanced Technology for Large Structural Systems) Research Center, funded by the U.S. Office of Naval Research, to study the design, fabrication and operation of ships with double hulls made of stainless steel and fiber-reinforced polymers.
In Australia, Semetay also shared details of his work on traditional welding cases such as backstep welding on T-beam. In this and other projects, Semetay uses AL6XN stainless steel in his simulations.
Semetay did welding simulations and calculations with Suraj Joshi, Abdul Kareem Alorier and Anna Paradowska who are graduate students in Monash's welding research group. He also met the group's advisers, Dr. John Price and Dr. Rafaat Ibrahim.
Semetay says he enjoyed taking trips in the Australian state of Victoria, including the Royal Botanic Garden, Grampians National Park, Phillip Island, Twelve Apostles and Great Ocean Road.
The journey required some adjustments - there is a 16-hour time difference between Pennsylvania and Melbourne, automobiles drive on the left side of the road, and it was summer in the southern hemisphere when Semetay traveled in January.
