Acoustic Black Hole Structures Using 3d-Printed Polymer Concrete, Siham S. Al Shanti

Civil Engineering ETDs

Mitigating unwanted vibrations is essential in the design of structural and mechanical systems to ensure safety, reliability, and long-term performance. This dissertation advances the Acoustic Black Hole (ABH) concept, passive vibration control strategy, by replacing geometric tapering with controlled material properties. Using Euler–Bernoulli beam theory, elastic modulus variation in polymer concrete (PC) enabled wave velocity reduction without compromising fatigue resistance. The high strength, excellent damping, and rheological properties of PC makes it ideal for 3D-printed ABH structures. This work examined bond performance between normal concrete properties, developed PC mixes with tailored rheological and mechanical properties, and evaluated their 3D-printability. A …
