If you are attending the Civil Engineering Building tour, please plan to meet on the third floor of the Science Teaching and Student Services (STSS) building near the entrance and lobby at 2:35 pm on Saturday, February 9 to check-in for the tour. A tour guide will escort attendees to the on-campus location at 2:40 pm.
The Civil Engineering building tour will be centered around the Materials Diagnostics of Damage and Defects (MD3) Lab in the Department of Civil Engineering. The centerpiece of the laboratory is a 3D Laser Scanning Doppler Vibrometer (SLDV); a system that allows 3D experimental reconstruction of vibrational and wave propagation fields in solids and structures. The system is capable of capturing extremely minute vibrations with amplitudes on the order of 100 picometers and frequencies that range from almost DC conditions to 1 MHz (ultrasonic range).
Researchers of the lab use the vibrometer for two purposes:
1) Reconstruction of the dynamic behavior of synthetic material systems with unconventional internal topologies, such as phononic crystals and acoustic metamaterials, which can be used as mechanical filters and isolators or as smart actuators/sensors;
2) To localize damage and other anomalies in solids and structures using wave methods and a variety of techniques for the post-processing of the experimentally acquired wave fields.
The visit will include a description of the laser vibrometer as well as an overview of the research activities conducted in the lab. Professor Stefano Gonella and Ana Johnson will be conducting the tour of the Civil Engineering Building.
There is no additional cost for this tour.
