May a double restabilization of the trivial path occurr at monotonically increasing compression force?
May movable constraints be exploited to attain target force–displacement curves?
We provide a positive answer to both of these questions in our paper: Koutsogiannakis, Bigoni, Dal Corso. Double restabilization and design of force-displacement response of the extensible elastica with movable constraints, European Journal of Mechanics - A/Solids (2022)

Short description: The past years have seen a renewed interest from the Physics community in Solid Mechanics. Condensed-Matter Physicists, for example, are sometimes revisiting problems of Mechanics and Materials understood to be “classical” by Mechanical Engineers. Such an interest has brought a reinvigorating stimulus to the Solid Mechanics community in the area of geometrically non-linear problems of thin or slender structures, meta- and programmable materials and actuators, multi-physics interactions (surface tension, fluid-structure, magneto- or electrostatic coupling, responsive materials such as liquid-crystal elastomers), singularities and localization, deployable structures, fracture path stability.
Our mini-symposium therefore encourages our colleagues and friends to celebrate structures and their remarkable performances in a broad range of settings and applications.

1 PhD position (36 months) within the EID-ITN Marie Curie project LIGHTEN, funded by European Union, is available at the University of Trento (Italy).
The student will be supervised by my colleague Diego Misseroni and myself (Francesco Dal Corso), and two engineers at the English company Tensys (where the student will spend 18 months). If you are interested, please read the below description and the attached announcement before to apply.
PhD subject: Instabilities in structural membranes under extreme conditions
Dates: starting from May 2021, 36 months duration with secondment periods in UK (18 Months) and Germany (2 Months)
Research Supervisors: Prof. Francesco Dal Corso (UNITN), Prof. Diego Misseroni (UNITN), Dr. David Wakefield (Tensys), Eng. Adam Bown (Tensys)
Objective: Failure in building skins and highly deformable structural elements results from subsequent material instabilities and from the loss of stability due to changes in geometric or loading conditions caused by extreme events. As such instabilities affect the structural safety and resilience, unveiling their governing mechanisms is essential for the design of lightweight membrane structures. The aim of this research is to disclose the failure mechanisms of ductile materials and soft systems through the analysis of material and structural instabilities. Although strain localization and necking as material instabilities have been studied for the process of metal forming, the equivalent analysis for polymeric thin sheets has never been developed and it is crucial for the rational understanding of the processes leading to failure. Mechanical models for material instabilities occurring in structural membranes will be developed. Snap-through instabilities of inflated membranes will be experimentally studied, thus highlighting multi-stable structural configurations [at UNITN for 16 months]. Through this analysis, the critical conditions that trigger instabilities of inflated cushions in facades of lightweight buildings will be revealed, especially under severe environmental events caused by climate changes, as the tempest and high wind loads. Wrinkling, another structural instability that likely develops in thin films in response of heatwaves or long-term viscous effects (creep, relaxation), will be numerically modelled and analysed in the context of real design cases [at Tensys-UK for 18 months]. The PhD student will also investigate the ponding stability of tensioned structures and will define safety factors associated with it [at SBP-Germany for 2 months]. Through the offered training, the young researcher will become a world-leader in the theoretical and applied analysis of structural and material instabilities that occur in thin films and lightweight structures.
Application deadline: January 18, Italian noon, 2021

Description of the Mini-symposium "Mechanics and Physics of Solids and Structures"

The past years have seen a renewed interest in the physics community for solid mechanics. Physicists, mainly condensed matter physicists, have started to revisit problems of mechanics and materials, thought to be classical by engineers and mechanicians. This renewed interest brought a research stimulus in the solid mechanics community. An example can be found in the theme of elastic structures where buckling, once thought as something to avoid, is now used to design and optimize systems: soft structures working in the post-critical regime are bringing new functionalities while still exhibiting excellent mechanical performances. Other examples can be found in biomechanics, the interplay between fluid and solids, growth and form, fracture mechanics.
The goal of this mini-symposium is to bring the solid mechanics and physics communities together for exchange of ideas, cross-fertilization, and new collaborations. We believe each community has its own tools and paradigms to bring: statistical physics on one side, and continuum mechanics on the other for example. We believe the emerging mechanics-physics community will be gathered around common tools (applied mathematics, nonlinear dynamics, proof-of-concept experiments, …) rather than a precise theme.
