slender body theory

The motion of filament-like structures in fluid media has been a topic of interest since long. In this regard, a well known slender body theory exists wherein the fluid flow is assumed to be Stokesian while the filament is modeled as a Kirchhoff rod which can bend and twist but remains inextensible and unshearable. In this work, we relax the inextensibility and unshearability constraints on filaments, i.e., the filament is modeled as a special Cosserat rod.

NewFrac Marie Curie ITN Workshop-2

Submitted by jose reinoso on
research

Dear friends,

 

I want to bring your attention for a modified dates for the NewFrac Marie Curie ITN Workshop-2

 

NewFrac Workshop-2 is especially focused on Phase Field and Finite Fracture Mechanics. It is open to senior researchers and PhD students in fracture mechanics.

Due to the covid situation, we announce that final dates for Workshop-2 are 9-12 May, 2022.

Competition between Mullins and curvature effects in the wrinkling of stretched soft shells

A highly stretched hyperelastic shell exhibits a coupling behavior of local wrinkling and global bending within the stability boundary, and curvature resists and can even suppress surface wrinkles beyond a critical threshold. Here, we report a novel phenomenon that smooth surface maintains upon stretching a soft shell, while wrinkles emerge upon unloading, which implies a nonlinear interplay between curvature and Mullins (stress softening and residual strain) effects in the entire loading-unloading cycle.

Thermally induced deformations in multi-layered polymeric struts

Stimulus activated structures that deform from a reference to target configurations are used in various fields such as soft robotics, smart materials, and actuators.  In this work we introduce a framework that captures the non-linear response of multi-layer polymeric beams subjected to thermo-mechanical loading. We show that the exploitation of the glass transition temperature can lead to a wide variety of interesting responses. Our findings provide guideline for an efficient design of shape-morphing structures capable of polymorphism.
