Plasticity

Dear Colleagues, 

within the 26th International Congress of Theoretical and Applied Mechanics (ICTAM2024) to be held in Daegu, South Korea, 25-30 Aug 2024, Henrik M. Jensen (Aarhus University, Denmark) and myself are organising the Thematic Session 'SM12 - Plasticity, viscoplasticity and creep'. 

We would like to invite you to contribute to this Thematic Session. 

The Extended Abstract Submission is open until January 15, 2024.

Best regards,

The 2023 edition of the advanced course on Modeling of Localized Inelastic Deformation, given by Milan Jirásek, takes place from 4 to 8 September at the Faculty of Civil Engineering, Czech Technical University in Prague.

One postdoc is sought to fill an opening in the Gross Materials Lab (group website: andrewjgross.com) at the University of South Carolina. This research is focused on extracting yield surfaces from data rich full-field experimental information by solving an inverse problem. This research will be primarily computational and will integrate closely with a graduate student conducting experiments. Applicants with relevant experience are strongly encouraged to apply.

Dear motivated PhDs of India, 

There is an opprtunity to work on experimental and numerical fracture mechanics using the prestigious National Post Doctoral Fellowship (N-PDF) by SERB India.

The details are available at: https://serbonline.in/SERB/npdf

We can have a discussion for a topic in Fracture Mechanics experimental and/or numerical. The scheme is opening on 3rd July 2023. 

Eligible candidates may contact me at : abhishek.tiwari@iitrpr.ac.in

My colleague Milan Jirásek is opening a two-year postdoctoral position in developing new regularized models for predicting and understanding failure processes under general conditions.

In this paper a geometric field theory of dislocation dynamics and finite plasticity in single crystals is formulated. Starting from the multiplicative decomposition of the deformation gradient into elastic and plastic parts, we use Cartan's moving frames to describe the distorted lattice structure via differential 1-forms. In this theory the primary fields are the dislocation fields, defined as a collection of differential 2-forms. The defect content of the lattice structure is then determined by the superposition of the dislocation fields.

The Advanced Computational Materials Engineering Laboratory (ACME Lab: https://acmelab.ua.edu) in the Department of Mechanical Engineering at The University of Alabama is seeking candidates for a fully-funded PhD position in the area of deformation mechanics to begin August 2022.

PhD position(s) is available for Spring 2022 in the Engineering Mechanics program in Aerospace Engineering Department at Iowa State University to perform theoretical and computational part of work on NSF-funded projects on the interaction between phase transformations and plasticity. Phase-field, micromechanical, and macroscale simulations using FEM are of interest, in close collaboration with high-pressure experiments performed in our lab. Please send vita to Prof. Valery Levitas ( vlevitas@iastate.edu )

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;

The microelectronics revolution is one of the most influential drivers of current industrial developments. To probe the mechanical properties of ever shrinking materials and components, nanoindentation has come to be an omnipresent and indispensable method. In a recent combined experimental and computational approach, an international team of scientists was for the first time able to resolve the dynamic atomistic processes taking place at the elastic-plastic transition during nanoindentation.

Dear Colleagues,

We would like to cordially invite you to the Computational Geomechanics mini-symposium at the ASCE EMI 2020 Conference, which will take place on May 26–29, 2020 at Columbia University in NYC. The abstract submission is now open until January 15, 2020 (Link: https://submissions.emi2020.org). The mini-symposium description is given below:
