    Feb 12, 2019 · 3 for this question: "What is the difference between strength, hardness and toughness in materials?" i have searched and have found these following definitions Strength …

  2. mechanical engineering - What is fracture toughness and how is it ...

    Jan 10, 2024 · Strength is just the amount of force that an object can take before breaking, so what is fracture toughness?

  3. mechanical engineering - What is meant by Material Toughness …

    Toughness is defined as ability of material to absorb energy when deforming before fracture. Materials with high ductility and strength will have high toughness. What is meant by ability of …

  4. mechanical engineering - Why are stress intensity units MPa√m ...

    Jan 3, 2023 · The units of stress intensity are usually taken as MPa√m. Cracks are usually measured in (mm), could someone please explain why this convention is used an not …

  5. materials - Brittle = highly stiff but not very strong - Engineering ...

    Nov 7, 2021 · Brittle is characterized by sudden failure without fore-warning as exhibited by the more flexible material. I think "stiff is a better word to describe a "strong" but brittle material. …

  6. materials - Stress strain curve stress and resilience - Engineering ...

    Apr 14, 2021 · It is technically a term only to be used for elastic behavior. After yield, the integrated area is the toughness. A plot below shows these concepts graphically. The area …

  7. strength - What is the physical reasoning behind metal becoming ...

    Sep 23, 2021 · 12 I was wondering that if a proper process of heat treatment (heating to a temperature above upper critical temperature, then soaking and then quenching) is applied to …

  8. materials - What do you call the steel property that reduces the ...

    Jan 29, 2016 · The answer would be more complete if it mentioned impact toughness, and maybe some tests of such: Izod, Charpy, Drop Test, etc. Just because a material appears tough at …

  9. How to find yield strength and Young Modulus from S-S curve

    Apr 13, 2021 · What you will need to do depends on the application and the underlying theoretical assumptions. E.g., for the young's modulus you can compute tangent moduli at each point and …

  10. energy - Why do some metals with bcc structure show ductile …

    Oct 24, 2020 · There is a library full of information . Mostly starting with WW 2 Liberty ship brittle fractures. But some going back to the Boston molasses tank failure of about 1900. The Naval …
