watching this 3 years after you posted them and I have to say they are the best I've seen. please consider doing videos on other subjects. Thanks a lot!
Thank you for the course prof. Schilder! I thoroughly enjoyed the videos and the clear explanations in combination with the lectures during the semester. Now the only thing left to do is pass the exam :)
Thanks for making the videos public. They were really well made. I am seeing this material for the third time now, twice before in university and I must say that your explanation was the best among the three in my opinion!
WOAH, this was your FIRST online course??? I absolutely loved how you taught it! I am sad you don't have lectures for the rest of my subjects! Or just more vibrations like with Fourier Series and such
Thank you a lot! The format of these mini-lectures really helped me get through, and with your enthusiasm it was even better and motivating. Hopefully you can inspire other lecturers to do the same and improve Hybrid-Education. I hope to pass the exam in one go.
Thank you for the lecture series. I really liked the overal structure, first a general introduction followed by the theory and some examples. It's nice to have all these lectures structured so well, I think this can help a lot during the preparation of the exam.
What a ride! This whole course had its highs and its twits and turns, with me not getting it, but in the end the whole plot fell together wonderfully. Jokes aside, many thanks Professor Schilder for these lectures, a great series!
Thank you so much! II really appreciate your teaching method. I covered almost all the topics from your provided course hope I will do my coming exam excellent.
Thank you very much for all the time and effort taken into this online course. I really liked the structured, well-explained, and interesting videos! I am confident to pass this exam.
Hi! Prof. Schilder, I am glad to learn about your mechanic vibration lesson, these lesson hello me a lot. to reduce the vibration amplitude of a centrifugal fan whose motor support bracket like a spider, I optimize the structure of the spider, which is like a cantilever system. I change the leg of spider structure from one beam to a trusswork, and the vibration amplitude was reduced. and I can't understand the relationship between the stability of structure and vibration amplitude. could you share me some know-how about this issue? may you have a nice day.
Thanks for these nice lectures. I really liked the way you go through the math ib a very logical manner. Can you also do a lecture on vibration of beams with a circular cross section?
Hey Jurnan, can you please make a video for vibration of a beam underwater(how the hydrodynamic added mass affects the natural frequency and mode shapes)?
That is not as straightforward as you may think, because calculating added mass and added damping coefficients depends on the location of the beam relative to the water surface and bottom. Also those coefficients are frequency dependent. What can be done relatively easily is computing the added mass for a beam surrounded by water in an infinite domain. You can interpret that as a beam that is far below the water surface. In that case the added mass is a constant and added damping is zero. The value for the added mass depends on the geometry of the cross section and it can be obtained from tables that you can look up online. Just out of interest: what do you need it for? Is there are particular application you are working on?
@@JurnanSchilder thank you for the quick reply. Yes I just started with my bachelor thesis. my aim is to find different ways to perform modal analysis of structures (basic geometries like a rectangular plate or a cylinder) submerged in water in Ansys and compare those results with analytical solutions.
I will teach a course Introduction to FEM later this academic year. This will be targeted to the second year bachelor students. For this course I will make a new series of video lectures. I hope you will like those as well!
@@JurnanSchilder PLEASE! this is very welcoming. I hope to have passed my resit, but either way I hope no other students has to endure iFEM without your lectures.

Wonderful video series, sir! Thank you so much for your lovely exposition.
Thank you so much for your lectures! Looking forward for your other lectures too!
Thank you for the videos. They were very enjoyable and clear.

I hope to get 11/10 in 2 months, amazing videos!
not in your university but this course has been invaluable! thank you🙏🏽

your lectures series are so organized and easy to find and understand any topic of interest in it
thank you a lot Jurnan
Thank you for your kind words.
Great... Very helpful ❤❤
the shape modes of the beam are in the jars !

thank you for the great video lectures. It was very very very helpful.
thanks prof greattings from panama latin america

Bro, you realize how important categorization is in education. That's why you are different.

Do you release your notes online?
Thanks very much for your courses. I was wondering… any chance of vibration of membranes? Plates?
Not in the near future, but I can highly recommend the book Vibrations of Continuous Systems by Rao for this!
sir wil you make videos on Finite element analysis
I will teach a course Introduction to FEM later this academic year. This will be targeted to the second year bachelor students. For this course I will make a new series of video lectures. I hope you will like those as well!
@@JurnanSchilder sir please start your series as fast as you can, it will help us a lot.
@@JurnanSchilder We'll be waiting for that Professor :)
