    It''s very interesting to see how things work practically instead of just reading it from books.

    No idea why this was in my recommendations, but I watched it and it was interesting. Props for Anneke Reinsperger for speaking English without even the hint of a German accent.

    Mechanical stress sigma is always defined as Force F divided by cross sectional area S (or area A). Or more precise: NOMINAL stress sigma equals force F divided by ORIGINAL cross sectional area S zero.
    In the video TWO physical quantities are plotted on the vertical axis: Force F on the right side and stress sigma on the left side. Sorry for this, it may be confusing. You get sigma on the left side by simply taking F and dividing it by the original cross sectional area S zero.

    In materials of medium or low ductility, the fracture may take place anywhere along the prismatic part of the specimen, mostly at a weak point. In very ductile materials, the fracture tends to form in the middle region, because there is a certain influence of the grip regions.

  • @MaterialsScience2000
    @MaterialsScience2000  Před 10 lety +17

    "Why does the machine not apply any additional force in the 'luda' (Lüder) area of the curve?": This is an important question, and a research topic of mine, please see our publ. "On the nature of the yield point phenomenon" in Acta Materialia. "And why does the machine apply less and less force right before final fracture?" This is due to "material instability": Here the strain hardening effect is not strong enough to compensate the strength decrease due to the decrease in cross sectional area.

    • @Fallenangel-si4bd

  • @MaterialsScience2000
    @MaterialsScience2000  Před 11 lety +9

    The term "elongation" in ASTM 615 indeed is not specified clearly. To my knowledge it can only mean "percentage elongation after fracture". So one has to put the fragments together and then determine the percentage plastic deformation after fracture has occurred.

    It is very useful to know the material

    • @MaterialsScience2000
      @MaterialsScience2000  Před 7 lety

      Answer to "It is very useful to know the material": Quite correct, the steel is a typical plain low-carbon structural steel, type S235JR. The aluminium alloy is a 2014 precipitation hardened alloy with about 4 % Cu and some small additions of Si and Mg.

  • @MaterialsScience2000
    @MaterialsScience2000  Před 10 lety +5

    "what would be if we take off tension on the middle of experiment for example on 18mm elongation. and apply it again?" Then an elastic spring-back parallel to the elastic straight line would take place, not to the original length, but to the plastically strained length of about 17.8 mm. On reloading, after elastic behaviour the original curve will be resumed, as if nothing had happened.

    "If this rod was a hollow tube or pipe how would the inner diameter be effected? Am I to assume that the point at which it would neck the inner diameter would increase roughly as much as the outer diameter decreases?" We do not have much experience on tensile tests of tubes, but as far as I know, the inner diameter at the neck will decrease, and the outer diameter as well, a bit more than the inner one. So from the side, the broken tube looks similar to the massive cylindrical specimen.
