Investing in America’s infrastructure: Faculty weigh in on what to address in proposed infrastructure legislation

Cars and trucks drive on an interchange with roads branching off in several directions.

A bipartisan group of senators has announced a $1.2 trillion infrastructure framework, which aims to make transformational investments in infrastructure for transportation, clean water, universal broadband, renewable energy, remediation of legacy pollution, and resilience to the changing climate.

PhD Student Creates Community through Virtual Book Club

Maria Warren holds the book "BUILT" by Roma Agrawal standing in front of trees and a brick building.

As the pandemic dragged into 2021, Maria Warren found herself reading more and more.

With Covid-19 shelving her go-to leisure activities like playing soccer and meeting friends for coffee, the PhD student turned to books in her spare time and decided reread one of her favorites: BUILT by Roma Agrawal.

Research Lays Foundation for Partial Cloaking of Holes in Elastic Plates from Stress Waves

Arash Yavari stands in front of shelves stacked with colorful books

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.

Marine Animals Inspire New Approaches to Structural Topology Optimization

PhD Student Emily Sanders, left, and Professor Glaucio Paulino, right, hold red 3-D printed models as they stand on a campus sidewalk surrounded by greenery.

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.

Research: Extending Origami Into Untethered Robots and Morphing Devices

This illustration depicts a multifunctional, magnetically responsive origami system, possessing distributed, untethered control capabilities.

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.

Small Imperfections Can Have Significant Impact on Origami Metamaterials

Red, navy blue and yellow paper folded into origami structures illustrate how the shapes change when pressure is applied.

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.

New Research in Origami Metamaterials Promises Wide Implications

Larissa Novelino, a Ph.D. student at Georgia Tech, has long black hair and is wearing a black shirt and a black mask ovrer her nose and mouth. She is standing next to a table showing several metamaterial prototypes at different scales. They are different colors and range in size from smallest to largest.

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.

Sherman Uses Emerging Technologies to Repair and Preserve Bridges

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.
