Pitt civil engineering researcher Piervincenzo Rizzo recognized with outstanding paper award from ASNT

PITTSBURGH (June 3, 2013) … Piervincenzo Rizzo, PhD, associate professor of civil and environmental engineering at the University of Pittsburgh Swanson School of Engineering, is the co-recipient of the 2013 Outstanding Paper Award from the American Society for Nondestructive Testing (ASNT). Dr. Rizzo and his co-author, graduate research assistant Xianglei Ni, were recognized for their article, “Use of Highly Nonlinear Solitary Waves in Nondestructive Testing” by the ASNT Journal, Materials Evaluation [Volume 70, No. 5, pp 561-569, May 2012] The Award will be presented at the ASNT Annual Conference in Las Vegas, November 4-7, 2013.

According to the abstract, “This paper proposes the use of highly nonlinear solitary waves (HNSWs) for the nondestructive testing (NDT) of structural materials. HNSWs are mechanical waves that can form and travel in highly nonlinear systems, such as in 1D chains of particles, where they are generated by means of a mechanical impact. HNSWs have a constant spatial wavelength and are characterized by the important property that their speed, amplitude and duration can be tuned by modifying the particles' material or size, or the velocity of the impactor (striker). In the study presented in this paper, the feasibility of HNSWs for the NDT of aluminum, concrete and composites was investigated. Specifically, this study evaluated the capability of HNSWs to assess debonds in an aluminum lap-shear joint, determine the initial setting of concrete, and detect impact-related damage in a composite plate.”

About Dr. Rizzo
Piervincenzo Rizzo’s academic and professional interests are in the fields of nondestructive testing/evaluation, structural health monitoring, signal processing and automatic pattern recognition for real-time prognosis of structural and biological materials, and implementation of embedded sensor network for the health monitoring of civil, mechanical and aerospace structures. Current works include: 1) the development of guided wave-based SHM methodologies for pipes; 2) the investigation of highly-nonlinear solitary waves for the noninvasive assessment of structural and biomaterials including structural buckling. Dr. Rizzo earned his Laurea (MS) in Aeronautical Engineering from the University of Palermo, Italy; and his MS and PhD in Structural Engineering from the University of California San Diego.
