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.

There is an immediate opening for a self-motivated PhD/MS student (Spring 2025) in the Aerospace Structures Reliability Laboratory at Auburn University, working with Dr. Wen Luo on modeling the stochastic nonlinear behaviors of aerospace structures and materials. Prospective students are welcome to contact Dr. Wen Luo at w-luo [at] auburn.edu.

The Manufacturing Laboratory in the Department of Mechanical Engineering at the University of Alabama is looking for a highly driven Visiting Research Professor to join the lab. Our group focuses on developing advanced surface engineering techniques, particularly laser-based methods, and conducting experiments to deepen our understanding of the microstructure-property-process relationship.

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.

The Department of Mechanical Engineering at the University of Louisville is seeking a highly motivated Postdoctoral Researcher to join our team. The successful candidate will focus on simulating the dynamic behavior of multiphase architected materials.

Key Responsibilities:

• Develop and implement advanced computational models to study the dynamic behavior of multiphase architected materials.
• Analyze simulation results and collaborate with experimentalists to validate models.

Qualifications:

I find quite remarkable how the combination of electro-chemo-mechanics modelling and phase field approaches has enable to develop mechanistic models for the longstanding problem of corrosion. The following paper summarises recent developments in this emerging field: https://doi.org/10.1557/s43577-024-00715-8
