Buckling in Rings

From oil drums to–yes–soda cans, liquid-filled cylindrical shells are everywhere. And, it turns out, these structures fail differently than empty shells or ones filled with a solid. Liquid-filled cylinders buckle in sequential rings, as seen in the video below. Researchers found that the buckling resulted from the shell softening and re-stiffening under the compressive load–repeating that process over and over for each ring. Their findings could help us detect containers that are in danger of failing. (Video, image, and research credit: S. Jain et al.; via Ars Technica)

The experiments were dramatic, here are the
spectacular simulations by Marino's team.

@mechanobio

So #actin would be able to start the #lumen opening, and then a switch to #osmotic pressure driven growth would allow further opening before #buckling of actin.
Interesting.

@preLights
And we also had a variant of your pathway C of #epithelial fold formation : folding by *tensile* mechanical #buckling

(Note: these are my hands on the photo, so technically this is my own's only and single published experiment!)

@fuzzyherbivore @haufegroup

after the winter, there comes the #buckling #spring ;)

@DudinLab bioRxiv link is broken in tour cross-post, so here you go without :birdsite: : https://www.biorxiv.org/content/10.1101/2023.01.17.524456v1

Looks like a great #buckling and/or #cavitation story! #biophysics #mechanobiology @mechanobiology

Buckling tissue to a ...straight line! Not the sort of #buckling we're used to, in #Drosophila mesoderm #actomyosin narrows #tissue in DV and tension builds up along AP until forming a wire that indents embryo... like a cheese wire.
