Mechanical engineering software: UNIVERSITY PARK, Pa. -- Chujie Gong, a Penn State senior majoring inwards biomedical engineering, late won minute prize inwards the undergraduate poster contest at the American Society of Mechanical Engineers’ 2018 International Mechanical Engineering Congress too Exposition (IMECE).
Mechanical engineering software: Gong’s poster, titled “Three-dimensional Full-Field Strain Mapping inwards Total Shoulder Replacement,” was based on inquiry he conducted amongst the Penn State Mechanics too Materials Lab that addresses the well-nigh mutual complication inwards amount shoulder replacement surgery, glenoid implant loosening.
Mechanical engineering software: The glenoid os is the socket of the ball-and-socket shoulder joint, too the five-year loosening charge per unit of measurement post-surgery is relatively high, anywhere from xv per centum to 44 percent. This is due to issues amongst the biomechanics of where the os too implant connect.
Mechanical engineering software: Previously, measuring strains too charge displacement on bones used a strain gauge, but this method exclusively measures surface changes. Gong too other researchers stimulate got developed an improved arrangement that combines mechanical testing amongst micro-x-ray CT scans, a type of high-resolution CT scan that tin stair out mechanical changes within a specimen.
Mechanical engineering software: Using a fresh-frozen glenoid specimen, the researchers conducted mechanical charge tests acre scanning the specimen, resulting inwards amount 3D charge strain mapping on the glenoid os during testing. Micro-CT images of the specimen were taken earlier loading too later the charge was stabilized. Then, a glenoid implant was cemented onto the glenoid os too to a greater extent than or less other serial of the same tests too mapping were conducted nether identical loading conditions.
Mechanical engineering software: This enabled Gong too his swain researchers to seat strains too displacement on the entire specimen, both within the specimen too on the surface, too how these strains too displacement changed amongst an implant inwards place. Being able to fully stair out the differences inwards charge strains too their effects stimulate got corking potential for improving shoulder implants for patients such every bit those amongst arthritis.
Mechanical engineering software: “To amend sympathize what the mechanics are similar where the implant too shoulder connect, nosotros take away to report what's changed within the shoulder os when you lot position a charge on it,” Gong said.
Mechanical engineering software: Jing Du, assistant professor of mechanical applied scientific discipline too caput of the Mechanics too Materials Lab, worked on the inquiry projection amongst Gong too said that this measuring method could termination inwards improved implant pattern too handling methods.
Mechanical engineering software: “By using our method, you lot tin quantitatively stair out the mechanics,” Du said. “This is non simply guessing. Previously, doctors made judgments based on experience, but nosotros tin hit quantitative insights straightaway based on engineering.”
Mechanical engineering software: Being recognized for his inquiry via minute house at a prestigious applied scientific discipline conference was non exclusively an observe for Gong, but likewise a surprise.
Mechanical engineering software: “This is a big honor, it was a big shock,” he said. “I'm a biomedical applied scientific discipline pupil at a mechanical applied scientific discipline conference, too thence that makes it form of surprising.”
Mechanical engineering software: As i of Gong’s professors, Du said that she was non surprised that he won this award.
Mechanical engineering software: “He is really humble, too nosotros know he is really good,” Du said. “This laurels is a really big encouragement for the squad to buy the farm on their work. It’s expert encouragement for everyone.”
Mechanical engineering software: Along amongst Gong too Du, others involved inwards the inquiry included Yuxiao Zhou, doctoral pupil inwards mechanical engineering; Apr Armstrong, professor of orthopedics too rehabilitation; too Gregory Lewis, assistant professor of orthopedics too rehabilitation too assistant professor of mechanical engineering, bioengineering, biomedical sciences, too applied scientific discipline skill too mechanics.
Mechanical engineering software: This inquiry was funded past times a Penn State College of Engineering Research Initiative (CERI) scholarship too Erickson Discovery Grant from the Penn State Office of Undergraduate Education. Gong received locomote back upwards from the Office of Undergraduate Education too the College of Engineering’s Office of the Associate Dean for Education.
