Collective behavior in the kinetics and equilibrium of solid-state photoreaction

Dear Colleagues,

Here is our recent paper published in EML on collective behavior in solid-state photoreaction. Combining statistical mechanics and continuum mechanics, we build a model to predict and explain multiple collective behaviors reported in experiments of solid-state photoreaction for the first time.

Vibration localization due to flutter instability in a bladed rotor

The current push toward lightweight structures in aerospace and aeronautical engineering is leading to slender design airfoils, which are more likely to undergo large deformation, hence experiencing geometrical nonlinearities. The problem of vibration localization in a rotor constituted by N coupled airfoils with plunge and pitch degrees of freedom subjected to flutter instability is considered.

Does roughness enhance or destroy adhesion????

Recently, Dalvi and co-authors have shown detailed experimental data of adhesion of soft spheres with rough substrates with roughness measured down to almost the atomic scale, finding that the Persson and Tosatti theory gave satisfactory predictions of the apparent work of adhesion during loading, once the increase of the surface area due to roughness is correctly computed at extremely small scales.

Postdoc in Mechanics/Tribology of Triboelectric Nanogenerators at University of Glasgow

Specifically, the post requires expert knowledge in experimental and/or computational mechanics of materials and/or tribology. The position is part of a large international EPSRC-SFI funded project aimed at developing next generation textile triboelectric nanogenerators (or T-TENGs) for powering of wearable electronics.  This position will focus on the mechanics and tribology of T-TENGs and will involve both modelling and experimental work.

EML New Year Message

Dear Friends of EML,

Happy New Year! 

2020 was an extremely challenging year for all because of COVID 19. For most of us, the lockdowns and work from home negatively impacted our research activities; for some, it provided a time to reflect on the value of our work; and, for a few, it presented an unusual opportunity to explore new directions of research.

USACM 2021 Call for Award Nominations

Nominations for the 2021 USACM Honors and Awards are now being accepted.  For information on guidelines and submitting nominations, go to this web page:

The deadline for submission is January 31, 2021.  As a past President of the USACM, I'd like to encourage members of the iMechanica community to consider suitable awardees and nominate individuals as appropriate.

Numerics of growth-induced deformations

Dear iMechanicians,

Growth-induced deformation or morphoelasticity  is an interesting phenomenon ranging from living tissues to biological plants in nature. We recently publish a paper in JMPS that solves some challenging boundary value problems by addressing few key issues in computational morphoelasticity. It might be interesting for you.

Jie Yin will be the next Editor of iMechanica Journal Club

Jie Yin of North Carolina State University will be the next Editor of the iMechanica Journal Club. The Journal Club was initiated in January 2007, soon after the launch of iMechanica. It has quickly grown into a flagship feature of iMechanica, epitomizing the vibrant topics and dynamic researchers at the frontier of mechanics.

Phase field predictions of microscopic fracture and R-curve behaviour of fibre-reinforced composites

Dear iMechanicians,

I hope that the following work is of interest to you. We combine the phase field method with cohesive zone modelling to predict the fracture behaviour of fibre-reinforced composites across scales.
