Kinetics of ferroelastic domain switching with and without back-switching events: A phase-field study
I am pleased to share our first open-access article of 2025! just published in #ActaMaterialia.
Leonardo's universal friction coefficient is found to be universal after all!
It turns out that friction coefficient 0.25 suggested as universal by Leonardo da Vinci more than 500 years ago has some universaility, as minimum friction coefficient for any granular material: it makes me proud as italian ;)
I guess it would be interesting to show this experimental result also theoretically or numerically, any interest?

Introduction
Invitation to MS - Recent Trends in Data-Driven and Computational Modeling of Materials Across Scales: From First Principles Calculations to Mesoscale Physics, at USNCCM18, 2025
Dear Colleagues,
We are organizing a mini-symposium 801 - Recent Trends in Data-Driven and Computational Modeling of Materials Across Scales: From First Principles Calculations to Mesoscale Physics, at USNCCM18, July 20–24, 2025, Chicago. We invite you to submit an abstract at this symposium. The abstract submission deadline is January 15, 2025. Please find the submission portal here: https://usnccm18.usacm.org/abstract-submission
PhD positions at Purdue – Artificial Intelligence for Multiscale and Multiphase Computational fluid dynamics
We have several openings for PhD positions. The successful candidate will conduct original research in computational fluid dynamics with special focus on AI and multiphase flows. They will develop numerical methods to be run on high-performance computing platforms. The positions are in the Gomez Research Group (https://engineering.purdue.edu/gomez/) in the Department of Mechanical Engineering at Purdue.

Postdoc position at Purdue – Large Language Models (LLMs) in Computational Mechanics
We have an opening for a postdoc position. The successful candidate will have a PhD in Mechanical Engineering or a related field, excellent programming skills, and knowledge of computational mechanics and Large Language Models (LLMs). The positions is in the Gomez Research Group (https://engineering.purdue.edu/gomez/) in the Department of Mechanical Engineering at Purdue.

Discussion of fracture paper #43 - Fracture Mechanics Contributes to Averting Our Planetary Climate Change Crisis
Fracture mechanics suddenly provides a step forward to stop climate change. The blogger has often pictured us humans walking on earth, asking ourselves how to get sufficient energy without burning fossil oil and destroying forests. Earth has a crust that is 30 to 50 km thick. Below it, the temperature is 1 to 6 thousand degrees Celsius. We are on the outside of a thin shell and inside is mostly melted rock, forming a sphere with a diameter that is close to 13000 km. For someone seeing this from another solar system, our behaviour must seem strange and pathetic.
CISM Advanced Courses on Wrinkling
Wrinkling - Theoretical Foundation, Experimental Characterization and Numerical Modeling
This course is aimed at graduate students, PhD candidates, and postdoctoral researchers in electronics/biomedical/mechanical/civil engineering, materials science, biophysics and applied mathematics. It is also valuable for senior scientists and engineers in academia and industry interested in the fundamental theoretical aspects of wrinkling phenomena, their numerical simulation and experimental characterization.
The Second Law as a constraint and admitting the approximate nature of constitutive assumptions
A scheme for treating the Second Law of thermodynamics as a constraint and accounting for the approximate nature of constitutive assumptions in continuum thermomechanics is discussed. An unconstrained, concave, variational principle is designed for solving the resulting mathematical problem. Cases when the Second Law becomes an over-constraint on the mechanical model, as well as when it serves as a necessary constraint, are discussed.
