Institute of Geosciences of Environment, St. Martin d'Heres

The Institut of Geosciences of Environment (IGE) is a public research laboratory under the CNRS/INSU, IRD, Grenoble Alpes University (UGA) and Grenoble-INP, and is looking for a researcher in numerical modeling of viscoplastic deformation behavior of rocks and ice, in the frame of the ERC project RhEoVOLUTION led by Andrea Tommasi (Geosciences Montpellier). The candidate will work in the CryoDyn team of IGE under the supervision of Maurine Montagnat, expected to begin 1 December 2020.

Activities

The ERC Rheovolution project, held by Andrea Tommasi from Geosciences Montpellier, aims at designing innovative tools and methods to simulated deformation and flow of rocks (including ice) at various scales. The innovative approach suggests to take into account heterogeneities and anisotropy in a stochastic way.

The person hired in the frame of this post-doctoral position will be in charge of developing new modelling tools for simulating the deformation of ice, by making use of the finite element library C++ Rheolef. This work will be done in collaboration with ISTerre and LJK laboratories.

  • Take over the development of a finite element code with the Rheolef library to simulate the viscoplastic behavior of ice, taking into account strain and stress heterogenities in a stochastic way.
  • Interact with the experimental part of the RhEoVOLUTION project to validate the modeling approach (an d better analyse the experimental results).
  • Ensure the interface with larger scales simulations by producing characterization of heterogeneities (probability density functions and their evolution) out of the finite element model.
  • Participate actively to the scientific exchanges in the frame of the RhEoVOLUTION project


Skills

Earth sciences, mechanics of materials.

  • Numerical modeling skills and knowledge of finite element calculation.
  • Good knowledge of plasticity mechanisms in materials.
  • Good knowledge of the Python language for model output treatment.
  • Very good practice of English.
  • Good reports and scientific articles writing skills
