The Curie brothers, Pierre and Jacques, discovered the piezoelectric effect in 1880. The phenomenon has been exploited in many useful applications, such as for the pickup on the gramophone that registers the sound when it follows the winding groove in the vinyl record surface. It is also used in lighters that ignite a gas when the voltage gap between different locations exceeds the limit to produce a spark. When things are made smaller and smaller, passing mm's, microns down to nano scales, the piezoelectric effect is surpassed by the flexoelectric effect.

I have an opening PhD Position at my Chair of Computational Mechanics, Otto von Guericke University Magdeburg (Germany).
The candidate should work on a research project including physics-based modeling of wafer-to-wafer bonding.
The application is open until 24^th of April.

``UNIFIED MICROMECHANICS THEORY of Composites” by Buryachenko has been created (see https:// arxiv.org/abs/2503.14529,  89pp, 514refs) for analyses of composites of either random (statistically homogeneous or inhomogeneous), periodic, or deterministic (neither random nor periodic) structures with either local, weakly nonlocal (strain gradient and stress gradient), strongly nonlocal (strain-type and displacement-type, peridynamics) or multiphysics phase properties and any unpredefined surrogate (effective) nonlocal operators.

A PhD position will be available at University of Pavia in Italy starting November 2025. 

Interested candidates are encouraged to contact Prof. Giulia Scalet (giulia.scalet [at] unipv.it).

The candidate will work on new computational approaches for the simulation of smart polymers and hydrogels and their application to mechanobiology studies. 

Extreme Mechanics Letters (EML) is thrilled to announce the appointment of Professor Xuanhe Zhao of the Massachusetts Institute of Technology (MIT) as Co-Editor-in-Chief of EML. Professor Zhao is a world-renowned expert in the mechanics of materials and soft robotics.

A compliantly fixed hemispherical indenter in adhesive contact with an elastic sample firmly bonded to a rigid base is considered under the assumption that the rigid base undergoes small-amplitude high-frequency normal (vertical) oscillations. A general law of the rate-dependent JKR-type adhesion is assumed, which relates the work of adhesion to the contact front velocity. Using the Bogoliubov averaging approach in combination with the method of harmonic balance, the leading-order asymptotic model is constructed for steady-state vibrations.

Dear members of the iMechanica community,

The deadline for abstract submission for the 
EuroSuperalloys - THE symposium for all things superalloy,
including modeling, DFT,  atomistic simulations and machine learning approaches for 
superalloys and metallic or intermetallic materials beyond superalloys -
is approaching fast: 31. March 25

For more information, see:
