Necking of thin-walled cylinders via bifurcation of incompressible nonlinear elastic solids

R Springhetti, G Rossetto, D Bigoni - Soft Matter, 2024 - pubs.rsc.org
Necking localization under quasi-static uniaxial tension is experimentally observed in ductile
thin-walled cylindrical tubes, made of soft polypropylene. Necking nucleates at multiple …

Elephant trunk wrinkles: A mathematical model of function and form

Y Liu, A Goriely, LA Mihai - arXiv preprint arXiv:2409.03075, 2024 - arxiv.org
A remarkable feature of the elephant trunk is the pronounced wrinkling that enables its great
flexibility. Here, we devise a general mathematical model that accounts for characteristic …
