granular materials

Multiple postdoc and one PhD positions are open at Tsinghua University to investigate mechanics and numerical modeling of granular materials and debris flows through a multiscale approach integrating experiments, simulations, and theory. The research will take place at Tsinghua University’s Shenzhen International Graduate School (SIGS), located in Shenzhen, China, and is partly sponsored by NSFC and Tsinghua SIGS’s scientific research startup funds.

Applications are invited for two postdoctoral positions in the Geomechanics Group led by Dr. Buscarnera at Northwestern University. Both positions focus on the multi-scale behavior of granular solids, with one emphasizing numerical and theoretical modeling of the particle-continuum duality and the other emphasizing the experimental study of particulate materials through advanced characterization protocols.

One postdoctoral position is immediately available in the Department of Mechanical and Design Engineering at Hongik University in Sejong, Republic of Korea. 

The postdoc candidate should have a strong background in computational mechanics of granular materials (especially, in particle-level high-speed contact/impact of solids), numerical methods (such as DEM and FEM), and computational code development with C/C++, Fortran and/or Python. 

I have a fully funded postdoc position with some flexibility for the starting date (Fall 2022, Spring 2023, Fall 2023) at Columbia University for a project on deep learning for dynamic responses of solids. More information can be at our research group website www.poromechanics.org. Candidates with a subset or all of the following skills will be considered:

1. programming skills (python and C++)

2. computational mechanics

3. micropolar and micromorphic theories

3. graph theory

EMI, the Engineering Mechanics Institute of ASCE, is pleased to announce the EMI announces the 2021 Student Video Competition organized by its Granular Materials Committee within the broad field of granular materials.

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;

I have an opening for a new postdoctoral scholar to join my research group, please see attached. The project is on the field-scale calibration of DEM models. Primary responsibilities include developing and executing large-scale experiments, interpretation and synthesis of results, and collaboration with modelers to perform the calibrations.

This work, dating back to 2015 demonstrates the simulation of grain morphologies for subsequent fabrication of surrogate geomaterials 

Abstract: Shear banding is widely observed in natural fault zones as well as in laboratory experiments on granular materials. Understanding the dynamics of strain localization under different loading conditions is essential for quantifying strength evolution of fault gouge and energy partitioning during earthquakes and characterizing rheological transitions and fault zone structure changes. To that end, we develop a physics-based continuum model for strain localization in sheared granular materials.

A postdoc position is available in the area of computational mechanics, in particular, granular mechanics and discrete element modeling (DEM), in support of a Department of Energy-funded research project on Integrated Process Optimization for Biochemical Conversion. This is a multidisciplinary research project with collaborations between multiple academic institutions and the DOE's Idaho National Laboratory.

The Hurley Research Group at Johns Hopkins University welcomes applications for PhD students to join the group in Spring 2018 or Fall 2018.

Summary 

Multiscale computation and modelling of granular materials
 

Granular materials are ubiquitous in nature and extensively utilized in many processes in civil, chemical, mechanical and mining industries.  Understanding and predicting granular material behaviour is vital for migrating natural hazards and for optimising industrial processes.  However, complexity arising from grain interactions poses considerable challenge to this task.  To date, there is no universal theory or model can describe granular material behaviour for a wide range of conditions.

A research position is now opening in the field of Computational Mechanics of granular materials, in Karlsruhe Institute of Technology (KIT), Germany. This position should start between May and September 2010, and is a full-time fixed-term PostDoc position for 2 years (TVL E13).

Fully funded PhD scholarschip for 3 years is available at the Institute of Geotechnical Engineering, Universität für Bodenkultur, Vienna, Austria. The research topic is the behaviour of granular materials. We expect a candidate with solid background in continuum mechanics and constitutive modelling. Some knowledge of DEM (discrete element method) will be a benefit. This project is financed by the European Commission within its Marie Curie Programme. There are some ten international partners in this project. During the project you will visit our partners in UK, Germany, Holland and France.
