1. Introduction

Prof. Zdenek Bazant (Northwestern University, USA) sent me a copy of the plenary lecture he delivered at Int. Conf. on Damage Mechanics 4 at LSU on May 15, 2023, to be posted. The lecture is about a critique of the theoretical inconsistencies in the Phase Field and Peridynamics techniques. Remarkably interesting talk that will create a significant discussion about the validity of these methods..

Dear all

Please fin attached a PhD proposal for the beginning of the 2023 academic year, proposed by the Institut P' (Poitiers, France) in collaboration with the LSPM lab (University Sorbonne Paris Nord), aiming at modelling fatigue crack propagations in metallic materials under gazeous hydrogen environnement.

The Materials Theory Group at the School of Materials Engineering of Purdue University has a postdoctoral opening in the area of phase field modeling of oxide film growth. The postdoc will use the phase field approach to investigate the growth of metal oxide films in an oxidizing environment, emphasizing the film grain morphology, composition, and stress distribution. The ideal candidate will have a strong background in phase field modeling with elastic effects and excellent computational skills. For inquiry, please email Professor Anter El-Azab (aelazab@purdue.edu). This position is part of a collaborative project with a materials research and software development company, and it will be available as early as April 1, 2021. The position will remain open until filled. Interested candidates can send a curriculum vita with list of publications, about half a page statement of research interests, and the names and contact information of at least two references. The Materials Theory Group performs theoretical and computational research in the areas of dislocation dynamics and mesoscale plasticity, radiation effects in materials, phase field method and applications to microstructure evolution in materials, phonon and electron thermal transport in crystalline solids, and computational methods for materials science and mechanics.
EEO/AA Policy:

Dear iMechanicians, I hope that our latest JMPS paper is of interest to you. We show how the phase field paradigm can be extended to model localised corrosion (aqueous electrolyte-solid interface) and the associated damage mechanisms.

Dear iMechanicians,

I hope this paper is of interest to you. We show that quasi-Newton methods make monolithic phase field fracture implementations very robust. Convergence and computations times orders of magnitude smaller than the usual staggered approaches are demonstrated in complex problems such as unstable cracking, fatigue or dynamic crack branching.

Abstract

PhD positions are open immediately in Advanced Hierarchical Materials by Design Labat Louisiana Tech Universityon multiscale modeling of materials under extreme conditions. This will be a collaborative project with MIT, Georgia Tech, and Idaho National Labthat is supported by Department of Energy.  The candidates must have earned a degree in Mechanical Engineering or related fields (applicants with a MSc will be given priority) and have a solid background in theoretical and computational mechanics.

A 1 year post Doctoral position is avalaible in France, on computational fractur mechanics. This is a join project between Univ. Paris 13 (LSPM lab), and Paris 7 (ITODYS lab).

The present postdoc subject is focused on the modeling cracking and buckling in thin films and nanostructures on stretchable substrate.

A PhD position is open for Spring 2018 in Advanced Hierarchical Materials by Design Lab at Louisiana Tech University on multiscale modeling of metamaterials. The candidates must have earned a degree in Mechanical Engineering or related fields (applicants with a MSc will be given priority) and have a solid background in theoretical and computational mechanics. Having knowledge of continuum mechanics, finite element modeling, and a programming language is a plus.

Prof. Wei Cai at the Mechanical Engineering Department of Stanford University is seeking a postdoctoral researcher to lead a project on the modeling of grain structure evolution in the surface layer under friction.  The major task of this project is the development of a phase field model for grain/sub-grain structure evolution under friction.  It is likely that molecular dynamics and dislocation dynamics simulations would be required as well to obtain a good physical understanding of the process.
