Feb 11, 2022 · So the Young's modulus, which is the ratio of (tensile or compressive) stress to the longitudinal strain, should be the same for both compressive and tensile stress.

Oct 10, 2018 · I want to know the Young's modulus for a compressive test, but I have just a tensile test. Are they of the same value?

Sep 13, 2015 · Since the change in length of an object is negative when compressive stress occurs, I would assume that, without a negative sign attached to the equation to cancel the negative change in …

Mar 23, 2019 · 5 I am trying to understand what bulk modulus is, but it is quite hard for me to understand it. I get that it is the resistance of material to compression from all directions, but what actually …

Aug 15, 2020 · The length used in the formula is the initial length of your specimen in the same direction of the load and the area is the cross-sectional area perpendicular to the direction of the load. Young …

May 6, 2021 · In my physics textbook, they have written that metals in general have a higher Young's modulus when compared to alloys. On the contrary, in the same chapter they have mentioned that …

Feb 9, 2022 · A nearly incompressible material has a slight change in volume, thus according to the formula of bulk modulus, the smaller change of volume means a larger value of bulk modulus.

Jan 17, 2024 · In addition to nice @Gandalf61 answer there's some caveat in what you propose. Original definition of thermal expansion is $$\tag 1 \varepsilon_0 = \frac {\Delta L} {L}$$, while you …

Oct 21, 2021 · Johnson thus notes that when designing for strength for curved contact, a low Young's modulus is desirable (the Young's modulus isn't a factor for yielding in the case of flat contact at the …

Jan 30, 2017 · The word 'stress' means exactly what it usually means in a technical context. It might help you to look up the relevant section to know that it is usually paired with 'strain' when discussing the …
