Computational/machine learning mechanics Postdoc/PhD position available at Columbia University

Dear colleagues, 

There is a new opening for one postdoc/PhD student position, to be filled immediately, in my research group in the Department of Civil Engineering and Engineering Mechanics at Columbia University. We are looking for postdocs/PhD in the broad area of computational mechanics. Candidates should have expertise and experience on modeling dynamic responses of path-dependent materials and software development. Our project is specifically focused on applications of machine learning for computational plasticity and damage.

Post-doc position in Mechanics of Materials at University of Houston

A one-year post-doc position is available in our research group at the University of Houston with a start date of 1 September 2021. 

We are interested in understanding how microstructural aspects govern material failure. Our approach relies on formulating theoretical frameworks that are informed by experiments and implementing them computationally.

Join us to expand in more novel directions:

(i) Data-driven plasticity and failure;

(ii) Phase-field approaches to plasticity and failure;

Project description:

How to incorporate a variable in damage model?

Hello every body,

I would like to use CDM (continuum damage mechanics) for modeling damage in my constitutive model and I need to incorporate a variable (or its effects) into my mechanical damage that doesn't evolve or change by time but changes by other factors (such as irradiation dose or etc..). Does anyone know of a paper which had been used the similar approach? I would really appreciate it if you can provide the link for me because I couldn't find any so far.

 

Regards,

Faezeh

Post-doctoral research associate and Graduate student openings

A postdoctoral and graduate student openings with the main focus on the mechanics of composites materials are available immediately in Shakiba's group. We are looking for strongly motivated candidates to work on an AFOSR supported project on 1) thermo-mechanical damage coupling in FRPs, 2) simulation of additively manufactured composites and 3) sensitivity and machine learning for damage predictions.

PhD scholarship application in Geomechanics at University of Lyon - Micromechanical and multi-scale behaviour of damaged heterogeneous rocks around underground excavations

 

Description:

The goal of this project is to investigate the multi-scale behaviour of clay rocks, going from microscopic to macroscopic scale, with application to underground drilling. The research will be based on multi-scale approach and numerical method allowing to model microstructure media in a double-scale framework (FEMxFEM). Please, see the full description in the attached file here below.

Postdoc Opening in Computational Materials Science at Rutgers University

The microMechanics of Deformation Research Group (mMOD) in the Department of Materials Science and Engineering at Rutgers University is seeking a Post-Doctoral Associate to participate in a pair of collaborative projects with a Department of Energy National Laboratory. The projects are focused on using discrete dislocation dynamics (DDD) simulations to understand dislocation patterning in deformed metals, and molecular dynamics (MD) simulations to understanding crack initiation in hydrogen-affected steels.

Dear colleagues,  We would like to make you aware of a mini-symposium we are organizing for WCCM-ECOMAS in 2020, to be held in Paris on July 19-24, 2020. The symposium is entitled "Computational Geomechanics", and focuses on modeling aspects related to geological materials.

What fatigue damage model do you suggest to use in numerical simulations?

I want to simulate fatigue damage of foams (like PVCs). What fatigue damage model do you suggest? What model is regularly used in Industry? is there any one who simulate fatigue damage in Abaqus? Any information is welcomed...  Thanks in advance

Dynamic response and localisation in strongly damaged waveguides

In this paper, we investigate the formation of band-gaps and localisation phenomena in an elastic strip nearly disintegrated by an array of transverse cracks. We analyse the eigenfrequencies of finite, strongly damaged, elongated solids with reference to the propagation bands of an infinite strip with a periodic damage. Subsequently, we determine analytically the band-gaps of the infinite strip by using a lower-dimensional model, represented by a periodically-damaged beam in which the small ligaments between cracks are modelled as ‘elastic junctions’.
