Teaching

Autumn semesters:

ME 5194 Engineering Acoustics

An introductory course on acoustics: the physics of sound and basis for human hearing. Topics include but are not limited to: air-borne wave propagation characteristics; principles of acoustic measurements; fundamentals and practices of architectural acoustics and noise control; human hearing characteristics and psychoacoustics.

A course syllabus is provided in the link.

The course notes are provided in the link.

2017 Spring semester:

ME 8260 Advanced Engineering Acoustics

The aims of this course are to (i) establish deep understanding of acoustic wave propagation physics and principles, (ii) understand linear wave propagation characteristics, including radiation, absorption, and transmission of sound from and through structures/materials, along waveguides, and within enclosures, (iii) acquire knowledge on computational tools used to investigate acoustic systems, and (iv) explore emerging areas of interest in the acoustical engineering community.

2015 Autumn semester:

ME 3260 System Dynamics and Vibrations

An extracurricular video project was assigned where the goal was to examine a concept covered in the course (or related to material therein) as observed and applied to a real-world problem. To complete the project, student teams submitted a short video where the project evaluation metrics were the "balance of 'info-tainment' and educational values" and the "integration of analytical and experimental evidence to examine concepts, prove model predictions (as needed), and illustrate discoveries". The resulting videos exemplified students' excellent comprehension of the course concepts and abilities to communicate their knowledge in engaging ways to a non-technical audience.

Some of the video submissions are shown below while others are provided in this youtube collection.

Outreach

2017 June 22. The LSVR and COSI (Center of Science and Industry) team up for a COSI Camp with a classroom of energetic students from the second/third grades representing diverse schools from the Columbus, OH, area. Dr. Harne, Shichao, and Chengzhe share about engineering structures and how shape governs the properties of structures. This provides the opportunity to explore origami as a pathway for structures that change properties because origami changes shape. The LSVR Team and the students fold origami structures and answer the question "What might these origami structures be used for?". Photos from the day are provided below.

Dr. Harne and Shichao share about engineering structures with the kids.

Chengzhe guides the folds!

Dr. Harne shows how to fold a Miura-ori with a camp student.

Shichao works with a student to complete the fold.

At some point, we are done folding and get to enjoy the origami structures that are created!

2016 Sept. 28. Students from the Metro Early College High School in the DESIGN Learning Center Program visit LSVR with their teacher, Mr. John Thesing. Dr. Harne, Quanqi, Shichao, and Chengzhe share with the Metro team about engineering and science research at OSU in the Department of Mechanical and Aerospace Engineering, and about the specific investigations ongoing at LSVR in acoustics and dynamics. The students get a hands-on experience of folding our "origami acoustics" specimens, learn about bistable structures with two stable shape configurations, and discover how constraints in elastomeric material systems can be used for shock attenuation and diffusion, such as in helmets. Check out the photo slideshow below for a glimpse of the day.

Dr. Harne and Shichao give the broad overview of research at OSU MAE and LSVR.Quanqi chats with the students before the day begins.Dr. Harne discusses the concept of hyperdamping.Dr. Harne describes how strain in oscillating structures can be turned into electrical energy.Students explore the folding acoustic transducers.Dr. Harne and Chengzhe share about the simple physics of guiding acoustic energy.The topic of origami acoustics is great interest for the team from Metro.
