Plasticity

ANSYS, Inc. has an immediate job opening in Houston, TX for a Technical Services Engineer.  This is a full time position.

The job entails providing advanced technical guidance on various aspects of computational Structural Mechanics to clients in industry and academia.

European Commission' s JRC (Joint Research Centre) is organizing a workshop on physics based modeling of material properties and experimental observations in collaboration with METU (Middle East Technical University). The workshop will be held in Ankara on 22-23 October 2012.

The Workshop will include lectures by keynote speakers: W. Curtin, F. Dunne, L. Malerba, J-F Molinari, A. Needleman and B. Svendsen, and presentations by participants (oral or posters).

Our group at North Carolina State University is hiring PhD students and Post-doctoral Associates in the areas of multiscale modeling, computational mechanics, fracture, and plasticity.

Interested parties should email  zikry@ncsu.edu, and send a cv with a few representative publications.

Attached herewith a classical paper by Hart on introducing a concept of constant hardness curves refuting that absolute strain should not be considered as a state variable.

The interesting part is he uses a stress relaxation test to prove the same. Stress relaxation test, here refers to a tensile test, where the test is stopped after say certain amount of plastic deformation. The stress drops a little, but the total strain is constant. However, it is argued that there is a small inelastic deformation, which is the cause of this load or stress drop.

The objective of the workshop, co-organized by Joint Research Centre of the European Commission and Middle East Technical University, is to discuss the present status of physics based constitutive modelling of metallic materials and associated experimental methods.

The Workshop is funded by the European Commission's Integration and Enlargment Programme.  There is no cost for attending the Workshop. A limited number of scholarships is available for participants from the target countries (see attached flyer).

Dear all,

We are pleased to announce the forthcoming Summer
School on “Hardening and Damage of Materials under Finite Deformations:
Constitutive Modeling and Numerical Implementation”, which will take place in
Dortmund, Germany from September 3rd to 7th, 2012 and is organized by Prof.
Dr.-Ing. A. Erman Tekkaya of TU Dortmund and Dr. Tudor Balan of LEM3,
ENSAM Metz.

Post Doc description:

Soil, as a typical natural material, has very complex behaviour which is very difficult to be accurately modelled. In geotechnical engineering, about half of the accidents are caused by insufficient designs. The soil’s constitutive model is the fundamental issue for modelling and analyzing soil-related engineering systems.

Two Masters' positions are now available for the winter semester (starting in January), 2013 on computational materials sciene in the Department of Mechanical and Manufacturing Engineering at the Unviersity of Manitoba. The potential student(s) will work on the thermostability and mechanical properties in nanocrystalline materials and crystalline/amorphous composites. Students with strong interests in atomistic simulations (MD, ab inito, monte carlo, etc.) and good programming skills (C, Fortran, etc.) are encouraged to apply. Intrested students please send a CV and inquires to Prof.

The Corinth Rift in Greece is one of the most active extensional regions in the Mediterranean area (Fig. 1). The Corinth Rift Laboratory project (CRL, http://crlab.eu) is based on the cooperation of various european institutions that merge their efforts to study fault mechanics and related hazards in this natural laboratory where numerous continuous observations are made. The present rift is asymmetric and deformation is very localized.

Dear friends and colleagues,

This is to inform you of the minisymposium

Plasticity: Bridging the Scales from Micro to Macro

to be organized at the 22nd International Workshop on Computational Mechanics of Materials (IWCMM XXII) and request you to consider submitting an abstract. The workshop will be held in Baltimore, MD, USA during September 24-26, 2012.

My co-organizers and I invite you to submit an abstract to the upcoming symposium “Multiscale Perspectives on Plasticity in Metals” at the ASME 2012 International Mechanical Engineering Congress & Exposition (IMECE), to be held November 9-15, 2012 in Houston, Texas. This symposium will explore the unique challenges to understanding plastic deformation in metals and formulating material models that can accurately predict thermo-mechanical deformation.

We anticipate the opening of four postdoctoral positions in 2012 to work on statistical aspects of fracture and plasticity,  and in particular on size effects in the fracture of  disordered media and in microplasticity.  The positions will be funded by the ERC Advanced Grant 2011, SIZEFFECTS.
