Ryan Holmes To Attend NSF’s NEES-REU Summer Program

Ryan Holmes, a SCE civil engineering student, was recently awarded an opportunity to attend the 2013 NSF’s NEES-REU Summer Program at the University of Nevada, Reno. This summer research program is designed for upper division undergraduate students interested in Earthquake Engineering. Ryan will spend 10 weeks at Reno and work on one of the NEES projects. The focus of his study will be on shake table modeling and seismic risk mitigation. As a part of the program, he will have the opportunity to attend a “Young Researchers’ Symposium” and the NEES Annual Meeting. Ryan Holmes has been working with Dr. ZhiQiang Chen in several research projects and has coauthored two technical papers. In the picture, Ryan Holmes (front) was preparing a unique dynamic fluid-soil-structure testing with Dr. Chen’s graduate student, Rahul Tripathi.

According to the National Science Foundation’s (NSF) Network for Earthquake Engineering Simulation (NEES) webpage, NSF “created the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) to give researchers the tools to learn how earthquakes and tsunami impact the buildings, bridges, utility systems and other critical components of today’s society. NEES is a network of 15 large-scale, experimental sites that feature such advanced tools as shake tables, centrifuges that simulate earthquake effects, unique laboratories, a tsunami wave basin and field-testing equipment. All are linked to a centralized data pool and earthquake simulation software, bridged together by the high-speed Internet2. The new NEESgrid system, a communications web that uses collaborative tools and tele-presence technologies, allows off-site researchers to interact in real time with any of the networked sites. With these tools, engineers and students from all parts of the country can collaborate on multi-site experiments using simulators that generate earthquake effects strong enough to bring down full-sized buildings.”

CE student Ryan Holmes to present ASME research poster in Puerto Rico

Civil engineering junior, Ryan Holmes, has been selected to present a research poster presentation (he is listed as the first author) at the ASME SBC (American Society of Mechanical Engineers, Summer Bioengineering Conference) in Fajardo, Puerto Rico on June 21st. Ryan became involved in the research effort about a year ago when he was invited to help with the testing of some developmental materials, after he finished a dynamics class with Dr. Jennifer Melander. Ryan observed, “The more I learned, the more I wanted to learn and further my understanding of chemistry, mixture design, material testing, and research in general. Dr. Melander describes this thirst for knowledge as the “thinking bug,” and I agree, though I hope to never find a cure!” Ryan now describes himself as a “civil engineering student, with an emphasis in being the most eclectic engineer.”

The name of his research project is “Polymerization Stress and the Influence of TOSU Addends on Methacrylate Composites.” His research efforts included testing and characterizing properties of dental resin mixtures (used for cavity fillings and tooth substitute, can be thought of as a “glue”) by examining their mechanical properties (flexural/compressive/tensile strength and modulus), determining their handling properties (exothermicity, viscosity, and cure time) and their chemical properties (FTIR spectra, polymerization stress, degree of polymerization). Analysis of the data required the use of MS Excel and statistical (ANOVA) software.

The research involved the collaboration of University of Missouri faculty researchers Dr. Jennifer Melander, Dr. Kathleen V. Kilway, Dr. Thomas P. Schuman and Dr. J. David Eick and UMKC student researchers Ryan Holmes, Bradley D. Miller and Rachel A. Weiler from different academic disciplines – chemistry, dentistry, and engineering. Ryan notes that “by studying polymers that reduce polymerization stress, we can provide better tooth fillings and glues. More importantly, it gives us insight as to how the polymer interacts with other additives. In other words, how do the molecules come together and build on each other when other building blocks are present? This might answer questions like, ‘does this molecule make the system stronger?’ The stress created by the glue as it hardens is thought to be a negative quality of almost all dental glues, since it reduces the glue’s ability to remain connected to tooth or implant. So by reducing the stress/shrinkage of the polymer (glue), stronger and more durable materials can be made.”

Ryan will continue his studies as a graduate student and doctoral student once he earns his B.S. of Civil Engineering.
