      That's great Matthew, retaining walls are coming next (in about 2 weeks). Looking forward to your feedback and discussion on that video.

    Excellent video series! My group is very appreciative. Feom time to time, we show them to our clients When we need to explain a concept that's hard for them to understand.
    Thank yiu for imparting knowledge and please continue enlightening the masses.

    Very good and clear explanation, I'm studying geotechnics right now and this video is really great. A video about the calculus of elastic and plastic deformation on triaxials would be great 🤪🤣
    Keep up the good work 🙌🏼💪🏼

      Hi Andrea, thanks for the comment. We are very glad you liked the video, we will keep building with more videos and increase the complexity slowly. It might be a bit early for complex stress states and plasticity yet but could come up in the future.

  • @veramae4098
    @veramae4098 2 года назад

    In Norway a farmer was having some kind of pit dug. The soil was piled up along the bank of a nearby river.
    And a sheer slide started.
    Evidently this land, some of the best farmland in Norway, is on top of a layer of clay. When it started sliding the whole layer slid taking, as I remember, about 4 whole farms with it. It is continuing sporadically.
    I'm still trying to wrap my mind around that. How did that bit of soil piled up on the river bank so destabilize the whole area?

    Shear resistance of a material is normally a third to a half of the the compressive resistance

    I was expecting to hear about the hydrostatic pressure gradient (or some equivalent for saturated soil) affecting the shear stability of a soil medium.

    • @TheEngineeringHub
      @TheEngineeringHub  2 года назад

      That will be coming up in the next videos when we go over slope stability. We felt that it was a bit too early to go too debt into stability.

    Hello nice presentation! But i have one question. If soil is totally dry (no water in voids) shear failure occurs when friction between soil particles is smaller then shear stress in the soil, and that's obvious when you think about it, BUT, what about wet soils or soils that are in groundwater (saturated soils)? Friction now is not intuitive and what is the mechanism of failure then?

    • @MKowalska
      @MKowalska 2 года назад +1

      As long as the particles in the soil are in contact the friction will be there. What happens in a saturated soil is that the positive water pressure decreases the stress that holds the particles together. This is knows as the 'Terzaghi's law' of effective stress. From the total stress coming from e.g. the total weight of the overburden (the weight of the soil column, including the soil particles and the water between them) we have to subtract the pore water pressure - this resulting stress is the one that is really important. As long as it is larger than zero, there will be some positive shear strength. If the soil is not fully saturated (unsaturated) some suction may exist between the particles - this is then increasing the effective stress and so - increasing the shear strength. The Coulomb-Mohr principle saying that (the shear strength) = (the effective normal stress) * (the angle of friction) holds true for all dry, wet and saturated soils.

    • @Veke96
      @Veke96 2 года назад

      So if effective stress is zero or very small any vertical load on that saturated soil will cause it to fail in shear?

    • @MKowalska
      @MKowalska 2 года назад

      @@Veke96 Any HORIZONTAL load will shear it. Yes. Unless it is a fine preconsolidated soil (e.g. clay that has been loaded before more than it is now) or very angular coarse soil (sand, gravel). In these cases the shear strength may be increased (up to some effective stress) by 'cohesion' being the effect of interlocking of the grains/particles. In soils the history of loading is important...

      Hi @dilipkumarpatel481, it ranges from video to video. This one was on the low end and took about 40-50 hours. Other video can take even up to 100 hours if the topic requires a longer explanation and the animations are more complex. Thanks for the comment!

    In practice, soil would not be able to carry increasing loads, even if well co fined because of firstly the particle crushing and secondly chemical changes due to high pressure

    • @TheEngineeringHub
      @TheEngineeringHub  Год назад

      Yup, you are absolutely right. But those types of stresses would be beyond a structural application.
