Plasticity
EC FUNDED WORKSHOP ON PHYSICS BASED MODELING OF MATERIALS, Ankara, October 22-23
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).
how to model user defined creep in ANSYS?

Hi,
Is there a place I can find explained examples or tutorials on how to model user defined creep in ANSYS?
I need to follow the creep law __> effective creep strain (e at time t) = S. T. e^(-H)
S=(a0)^t.(sigma)^(a1) ; T = t^(a2)+(a3).t^(a4)+(a5)t^(a6) ; H = (a7)/[(theta)+273.16]
a0 to a7 are material constants.
I have the experimental data and tried to fit the curve in Ansys to obtain the material constants.

ENSAM Metz.
Post Doc Position: Risk-based Selection of Constitutive Models for Geotechnical Analysis, EC Nantes (France)
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.
Notched tensile specimens and force-displacement response.
Dear forum members,
I'm trying to simulate a tensile test (of ductile material) using smooth and notched specimens. I've started with a simple model without damage (isotropic von Mises plasticity implemented in ABAQUS) to compare the force vs. displacement response between simulations and experiments.
MSc position in computational materials science at the University of Manitoba
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.
Deformation rates and localization of an active fault system
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.
