Talk:Stick–slip phenomenon

Slip stick effect on conveyors

Hi, any information out there regarding surging or pulsation of conveyors ?

Hi i am investigating it now. So far it seems that there are 2 main parameters witch has the biggest influence. 1) the flexibility of the conveyor chain what is also often a result of the length. 2) the difference between static and dynamic friction. —Preceding unsigned comment added by Johnbroers (talk • contribs) 06:44, 10 February 2010 (UTC)

Violins and Bows

Not mentioning the most common and important application of a welcome sick-slip motion is ridiculous! Ever heard of making violin strings vibrate by the friction of the bows hairs impregnated by some rosin? And, less welcome: sometimes a pice of chalk on a blackboard? — Preceding unsigned comment added by 93.221.232.158 (talk) 13:20, 3 September 2011 (UTC)

In the examples section bowed instruments are mentioned specifically. Mikenorton (talk) 15:33, 3 September 2011 (UTC)

Multiple issues

I added a Multiple Issues template to the top of this article, because it's a bit of a mess, especially the "Cause" section. It mixes technical and nontechnical language, is structured in an illogical order (starting with a highly theoretical discussion of phonons before moving on to a phenomenological engineering description), and doesn't cite enough sources in the description. The "examples" section is well-sourced but reads like an indiscriminate list of bullet points. I will try to put some work into this article in the coming weeks but other contributions are welcome.

I have updated the article by adding some references, removing unsourced and excessive examples, and cleaning up the text to make it more readable to non-scientific audiences. I am on the fence about whether the engineering diagram of the spring and the load needs to stay, but I'll let it stay for now. Template removed since I think the issues are now mostly resolved.

I think the diagram is OK, and the removal of the template. What is certainly missing are links (I added some), and also connections to friction/tribology/nanotribology articles. A few other refs, e.g. Bowden-Tabot on asperities could be useful. I am not a big fan of the External Links here.

N.B., I did some ce as well -- friction does not "cause" things, it is a consequence. Ldm1954 (talk) 15:12, 18 October 2023 (UTC)

N.B., the old "cause" in terms of phonons is nonsense. Asperities, dislocations, plasticity etc are more standard depending upon the scale. You might want to include the standard FKT model, although it is oversimplified and sometimes musunderstood Ldm1954 (talk) 15:18, 18 October 2023 (UTC)

I removed the sentence referring to phonons, which I'm not sure I accurately summarized anyway. If you or anyone else has a better source or summary for that statement, please add back. WeirdNAnnoyed (talk) 18:26, 18 October 2023 (UTC)

My comment was not clear. For a very smooth interface the phonons are plausible -- my fault. What I should have said is that the old "cause" section from some time ago which indicated that pinned phonons were always the cause was nonsense. I will try and add some more in a few days, I have non-WP priorities first. (There is not just one sources.) Ldm1954 (talk) 18:36, 18 October 2023 (UTC)

WeirdNAnnoyed (talk) I added some more on the description with an extra figure and a couple of good books. Let me know if there are things which are not clear enough. Thanks in advance. Ldm1954 (talk) 18:32, 19 October 2023 (UTC)

That looks good! Thanks for clearing it up. Sources seem ok...a month ago this article was a wreck, so thank you for helping me bring it up to snuff. WeirdNAnnoyed (talk) 00:41, 20 October 2023 (UTC)
