Clarifying the non-uniqueness in Polarization

For ionic and dielectric materials, the polarization (dipole moment per unit cell) is plagued with non-uniqueness. As a 1D example, consider a 1D line of alternating positive and negative charges. If we agree that the dipole is a vector from the negative to the positive charge, then we have two choices for the dipole. This is because every negative charge has two different positive charges in its immediate vicinity. The situation gets more complicated in higher dimensions.

PhD position on wave-ice interaction at Aalto University, Finland

Hello,

 

We are looking for a doctoral student to work on wave-ice interaction. The emphasis in this research is on experiments in the 40m x 40m Aalto Ice and Wave Tank with a novel wave-maker, and our interest extends to ship-wave-ice interaction. The position is fully funded for four years and may include also field work.

hyper and probably over-prolific scientific authors (Nature article)

dear friends

Nature reported in Dec.2023 that up to four times more researchers pump out more than 60 papers a year than less than a decade ago. Saudi Arabia and Thailand saw the sharpest uptick in the number of such scientists over the past few years, according to a preprint posted on bioRxiv on 24 November.

FABER (Fatigue Benchmark Repository) to be funded by COST. Join us!

A dream came true, and the fifth submission of this networking project to COST Association was approved for funding.

 

It will start from November 2024 for the total duration of 4 years. The broad cooperation will focus on developing tools and data sets, which can streamline research and validation of fatigue estimation criteria.

MIT Short Course: Machine Learning for Materials Informatics (Jul 29 - Aug 2, 2024)

Dera iMechanica Community,

Below is information about a short course I will be offering at MIT this summer, in Live Virtual format: Machine Learning for Materials Informatics (Jul 29 - Aug 2, 2024).  This is an exciting opportunity that will cover fundamentals and applications in the emerging space of AI/ML for engineering, featuring hands-on interactive code development in Jupyter notebooks. We'll do a deep dive into all critical tools from autoencoders to graph neural nets to multimodal LLMs and multi-agent modeling. Please reach out to me if you have any questions.

Length scale insensitive phase-field fracture methodology for brittle and ductile materials

Dear colleagues, I would like to share our new article (open access) that presents length scale insensitive phase-field fracture models for brittle and ductile fracture to address the deficiencies of the widely implemented models which over-estimate crack dissipation.

Cancelling the effect of sharp notches or cracks with graded elastic modulus materials

Dear colleague

   I wonder if you could be interested in this idea of "Cancelling the effect of sharp notches or cracks with graded elastic modulus materials", particularly if you know who could help doing some experiments. Thanks for any comment, since this is a preprint it would be useful to discuss to make improvements.    RegardsMike    Cancelling the effect of sharp notches or cracks with graded elastic modulus materials

A phase-field model for study of ferroelastic deformation behavior in yttria stabilized zirconia

Dear colleagues, our new article (open access) is just published in Acta Materialia. In this research, we provide new insights into the mechanism of ferroelastic deformation by studying the evolution of domains in different microstructure patterns and under different loading directions and strain rates.
