The U.S. National Science Foundation awarded a team that includes Penn State Shenango, Sharon, Pa., and Youngstown State University, Youngstown, Ohio, $445,515 to explore the fatigue behavior of 3D-printed materials.<\/p>\n

The funding, known as a major research instrumentation grant, will support the acquisition of instrumentation designed to test both the dynamic stiffness \u2014 or how much a material deforms when force is applied \u2014 and the lifetime of a material subjected to external forces. The machinery will be housed at Youngstown State University in Ohio, about 30 miles from Penn State Shenango.<\/p>\n

Matthew Caputo, associate teaching professor of engineering at Penn State Shenango, is focused on the research capabilities of additive manufacturing, better known as 3D printing, of nickel-titanium shape memory alloys (SMAs). SMAs are a unique class of materials that have the ability to \u201cremember\u201d their original shape after deforming.<\/p>\n

\u201cThink of a metal coat hanger permanently deforming when it\u2019s pulled and twisted,\u201d Caputo said. \u201cIf the coat hanger was made with nickel-titanium SMA, the coat hanger would return to its original state after being deformed.\u201d<\/p>\n

According to Caputo, the material has difficulty in manufacturing processes, especially in complicated shapes. However, there is significant interest in using 3D-printing technology as a method to produce SMAs.<\/p>\n

\u201cThere has been some success [using additive manufacturing technology], but material fatigue, one of the most important aspects for applications, has yet to be fully explored,\u201d Caputo said.<\/p>\n

Fatigue, in the instance of manufacturing technology, is how well a material responds mechanically to a cyclic load. A portion of the grant was used to purchase an Acumen 12 electrodynamic test system, which is used to perform dynamic and static tests on different materials.<\/p>\n

\u201cNickel-titanium happens to respond favorably to fatigue cycles,\u201d Caputo said. \u201cThe focus of my work will be on creating 3D-printed nickel-titanium parts using additive manufacturing technology and testing their fatigue responses.\u201d<\/p>\n

Penn State Shenango students will have access to this state-of-the-art equipment as well. Local manufacturing industry representatives will be invited to participate in new research and development initiatives, enabling students to be involved in hands-on learning opportunities with real-world benefits.<\/p>\n
