The International Centre for Mechanical Sciences (CISM), based in Udine (Italy), has opened a call for applications to allow small groups of researchers in mechanics, two to four coming from different institutions, to spend two to four weeks at CISM during the year 2025 to start or to complete a joint research project.
Applicants should hold a PhD on a subject related to Mechanics, and there are no restrictions on their academic seniority.
Many researchers and engineers view mechanical fatigue of metals as a stagnated field, evidenced by the lack of substantially novel design approaches against fatigue in recent decades. However, our current capability to investigate, probe, and model the multiscale mechanisms of fatigue damaging processes may turn out to be pivotal for next-generation paradigms for the assessment of fatigue.
I am happy to share our newest open access article which is just published in Scripta Materialia. For the first time, the mechanism of domain nucleation during ferroelastic domain switching is revealed by utilizing phase-field simulations. Due to relaxation of strain energy, the coherent domain walls of the surviving domains often form features like steps, crevices and corners, and nucleation of new domains primarily takes place at these sites in a repeated fashion. Our work described the mechanism of ferroelastic domain switching to be independent of the domain wall energy.
For a given material, \emph{controllable deformations} are those deformations that can be maintained in the absence of body forces and by applying only boundary tractions. For a given class of materials, \emph{universal deformations} are those deformations that are controllable for any material within the class.
FABER networking project is funded for next four years by the COST Association. Its goal is to solve the current deadlock in validating the metal fatigue life evaluation methods and solvers by establishing benchmark sets of curated experimental fatigue data, with the focus set on the high-cycle fatigue category above all.
We have developed a mechanical transistor that synergizes a Kirigami thermomechanical sensor and a bistable actuator, enabling in-memory computing for combinational and sequential logic.
Our mechanical computing device stands out by employing modular construction, symmetry breaking, nonlinear materials, crafting logic gates and memory units responding to environmental stimuli through thermal delay.

I am happy to share our newest open access article which is published in Computational Materials Science. For the first time, we were able to create the t’ phase of yttria stabilized zirconia from its cubic phase through the process of rapid quenching by utilizing molecular dynamics simulations. The simulation of quenching process followed the experimental procedure, and the results of virtual XRD and RDF were comparable to the actual experiments, verifying the created phases.
Dear Colleague
It is known that ahead of a crack subject to static or fatigue loading microcracking and damage makes the material soften (of smaller elastic modulus) but also its strength degrades (in composite materials, there are so called “wearout models” which associate strength reduction exactly to the reduction of modulus).
