Dear colleagues,
We are pleased to share with you and invite you to read our work on energy conserving space-time metamaterials/media which has been published in Applied Physics Letters (selected as Editor's pick). The link to the online version is pasted below:

Title: An energy conserving mechanism for temporal metasurfaces
Exceptional points (EP) are non-Hermitian degeneracies where eigenvalues and their corresponding eigenvectors coalesce. Recently, EPs have attracted attention as a means to enhance the responsivity of sensors, through the abrupt resonant detuning occurring in their proximity. In many cases, however, the EP implementation is accompanied by noise enhancement, leading to the degradation of the sensor’s performance.

Composite tape-spring hinge (CTSH) is a simple yet elegant mechanical component for various deployable space structures. This paper formulates and addresses cut-out shape optimization of a CTSH, which is seldom touched upon in literature. Both the maximum strain energy stored during the folding process as well as the maximum bending moment during deployment were maximized in a concurrent way, and the multi-objective optimization problem was realized by merging data-driven surrogate modeling and shape optimization.
Please take a look at the paper of our PhD student Beatrice Bisighini in Advances in Engineering Software: "EndoBeams.jl: A Julia finite element package for beam-to-surface contact problems in cardiovascular mechanics". We propose an efficient framework for modelling beam-to-surface contact, specifically designed to model endovascular devices.

Dear iMechanicians,
I want to share our recent work published in IJSS on the mechanics of spontaneously formed 2D crystal bubbles.
