Fracture of Soft Materials (Fall 2023)


In this course, students will develop a comprehensive understanding of the mechanics of soft materials and learn about their fracture, fatigue, and adhesion. In addition to theoretical concepts, students will also be introduced to various experimental methods used to measure the mechanical and fracture properties of soft materials.

Anonymous Student Quotes

"Junsoo ensured students learnt the important core concepts, not just the applications required for problem sets."

"Junsoo is one of the best teachers I have had here, everything he says is useful to understanding. I looked forward to every one of his sections. He is enthusiastic and shares all of his knowledge!"

"I don't think I've ever learned so much and so much useful information in any of my classes before. I really felt like I settled into being a future mechanical engineer this semester."

"This is a hard course, but the staff are here to help you and if you want to succeed they will help you, and you will succeed."

"I have never met a more iconic teaching staff"

"Junsoo was excellent and explaining the problems and material in a logical, clear manner. Very accessible outside of class."

"Junsoo is one of the nicest people I have met, and he is an incredibly effective TF. He is always available to answer questions and is very thorough in his replies."

"Junsoo was by far the kindest and most helpful out of all the TFs. I really appreciated how flexible he was and available he was for additional instruction. He was encouraging and willing to take the time to explain any of the concepts covered in the course as well as more theoretical questions outside the scope of the course."

"Junsoo was the type of TF you would adjust your schedule to attend his section. He always had a smile on his face and you can feel the enthusiasm from him at all times."

"I did not have Junsoo for section, but attended his office hours. Junsoo really aimed to give fundamental understandings along with helping us understand the problem. The amount of time he spent helping me work through weird questions and applications I came up with really helped me get a better grasp of the material. He was also always very accessible outside of class."
