In their latest research into the feasibility of cloaking, Professor Arash Yavari and Dr. Ashkan Golgoon, PhD CE 20, found that while it’s not possible to fully protect plates from stress waves, a partial protection—or cloaking— is possible.
A mollusk and shrimp are two unlikely marine animals that are playing a very important role in engineering. The bodies of both animals illustrate how natural features, like the structures of their bones and shells, can be borrowed to enhance the performance of engineered structures and materials, like bridges and airplanes.
A team of researchers from The Ohio State University and the Georgia Institute of Technology has extended the possibility of origami, the ancient art of paper folding, for modern engineering applications such as untethered robotics and morphing devices.
The researchers demonstrated for the first time a multifunctional, magnetically responsive origami system, possessing distributed, untethered control capabilities. The untethered magnetic actuation separates the power source and controller out of the system, allowing scalable applications.
There is much interest in the possible use of origami-inspired metamaterials for engineering applications, due to their precisely architected structures that exhibit unconventional behavior. In practice, however, these structures are unlikely to exist without defects and imperfections.
Professor Glaucio Paulino has been selected as the winner of the Daniel C. Drucker Medal from the American Society of Mechanical Engineers. The Drucker Medal was established in 1997 and is conferred in recognition of distinguished contributions to the field of applied mechanics and mechanical engineering through research, teaching and service to the community.
The simplicity and elegance of origami, an ancient Japanese art form, has motivated researchers to explore its application in the world of materials. New research from an interdisciplinary team, including Northwestern University’s Horacio Espinosa and Sridhar Krishnaswamy and the Georgia Institute of Technology’s Glaucio Paulino, aims to advance the creation and understanding of such folded structures for applications ranging from soft robotics to medical devices to energy harvesters.
PhD Student Trent Schreiber has received a SMART Scholarship from the U.S. Department of Defense. The Science Mathematics and Research for Transformation (SMART) scholarship is a scholarship-for-service program established to enhance the Department of Defense workforce with talented, innovative and brilliant scientists, engineers and researchers.
Most of us take for granted the roads and bridges we travel every day. What we don’t know is that almost four in 10 bridges are 50 years or older. Many of the nation’s bridges are approaching the end of their design life, and 614,387 bridges in the U.S. earned a grade of C+ on the American Society for Civil Engineering’s 2017 Infrastructure Report Card.
While perhaps not as iconic as the paper crane, the hypar origami with its sweeping opposing arcs and saddle shape has long been popular for artists working in the paper folding tradition.
Now researchers at the Georgia Institute of Technology and the University of Tokyo are looking at the shape with an eye toward leveraging its structural properties, hoping to find ways to harness its bistability to build multifunctional devices or metamaterials.
