    Even as an engineer I have to say that your videos are very good. Obviously at university you will get a very detailed view of these topics but you summarize them very well.

      I gave you a thumbs up but I have to say it is still depends on what university. I studied at 1 of the top universities in Japan, but the class doesn't have 3d visual explanation and go in depth as much as this.

  • @cookiemaria780
    @cookiemaria780 4 місяці тому +1

    Something that has been confusing me for a long while, is the relationship between ductility and toughness. As far as I understand, ductility is a measure of the ability to plastically deform. I also understand that the plastic deformation is the main way that energy is absorbed by the material before fracture. This leads me to believe that materials with high ductility must have high toughness and vice versa, since toughness is the ability to absorb energy before fracture. However, i have seen some things online claiming that high ductility and high toughness do not always go together, and that even some ceramics are tough even though they are not ductile. Can someone please explain this to me? Like how can some ceramics be tough but then not plastically deform? How is the energy being absorbed in this “tough” ceramic? Are toughness and ductility not directly proportional?
    I need this info for university, would be really grateful for help.
    Incase anyone reading this is a German speaker, I have a further confusion, that I would love help with. As far as I understand, the translation for the German word ‘zähe’ is ‘tough’ and the translation for ‘duktil’ is ‘ductile’. In german ‘zähe’ seems to be used interchangeably for ‘duktil’, which in english would mean that toughness = ductility. But I can’t believe this is true. We can clearly see that ductility and toughness have different quantitative values. Are the terms used liberally in German? Was ist der Unterschied zwischen zähe und duktil? Bedeuten sie das gleiche auf deutsch? Was ist dann toughness auf Deutsch? Hilfe!

  • @דירהלמכירהברעננהדניאלרימקס

    Dear engineer
    I rigorously follow your videos and I don't think there is any student who doesn't understand them. Thank you very much for the explanations.
    Generally, in all the videos where -TAU- the shear stress (of the steel) is needed, the value of this is more or less 0.6 of the normal stress.
    Like the shear stress I would like to know (in the case of two plates that rotate on a steel link) in order to be able to know THE necessary THICKNESS of the plates that are not produced in them flatteningas, the flattening stress is calculated , of the steel?

  • @syaketyadav6310
    @syaketyadav6310 3 роки тому

    I saw you finally define ductility well but showing the range of ductility from beginning to the end on the stress-strain curve which I thought is not correct, it should be from yield strength point to till fracture point.

    • @KumarHemjeet
      @KumarHemjeet 4 роки тому

      Softening temperature is the temperature at which material will become relatively soft at higher temperature i.e flat ended needle penetrates to a depth of 1 mm under a specific load while DBT is the temperature below which material behaves as brittle.

    I got a doubt. How are the large stress concentrations at crack tip of a brittle materials (in contrast to plastic deformation which reduces localised stresses in ductile materials) a factor for having compressive strength greater than tensile strength in brittle materials?
