    Watched zillion videos to understand mode shapes, no one explained it as beautifully as you.

      Zillion is a really impressive number :-)
      We are all the more pleased that we were able to explain this complex topic in an understandable way also.

    A definition of modes based on linear algebra theory is so much much more satisfaying! A mode is just one axe, one dimension of an infinite dimension space. It blows the mind to realize that there is complete analogy between a 3-D dimension space and a modal space. To imagine a stationnary wave as one axe of a basis is just unbelievable, but it's true. Teh imagination can't accept this analogy, but using mathematicz, we can see the perfect analogy in particular the orthogonality property.
    In 3d-space, what is growing, it's the length of th (x,y,z) -axis for example, but in a modal space, what is growing, it's the amplitude of the specifics waves.

    Great Analogy
    Personally I may not agree in some point regarding the properties and other definition but I will definitely prefer and use the similar analogy for explaining others. Thanks to the team for providing complex knowledge in simpler form.

    Im quite confused about the theory of dynamic stiffness,hope you could break it down!

    • @HEADacousticsInternational

      Indeed, this is a confusing topic. :-) Here is our solution:
      On the 8th of October there is a free online seminar about Transfer Path Analysis (TPA) which will explains this topic in total. Just search for "HEADucation" and register for this seminar. You are welcome!

    so are mode shapes those point at which each DoF reaches it's natural frequency?

    • @HEADacousticsInternational
      @HEADacousticsInternational  4 года назад

      If you mean degree of freedom in the sense of a vibrating mass, then yes. Reality is more complex :-)

  • @viharize

    Does mode shapes get influenced by stress over the body??

    • @HEADacousticsInternational
      @HEADacousticsInternational  4 года назад

      Yes, this effect exists. For example: Components that have not been hot-annealed again. This can cause considerable detuning of resonances in sheet metal parts. Look for "residual stress"

      We're glad we could help you get started.
      We have many more videos here that will help you overcome the typical difficulties in understanding modal analysis.
      Enjoy!

    If u throw it out of the plane,the person on which it falls will definitely have his/her mode shapes changed
