Electrochemical permeation and thermal desorption spectroscopy by working on samples of mono and bi crystals

The LaSIE Laboratory at La Rochelle University proposes a 6 months internship at master degree level starting from January 2022 which will lead to a Ph.D position starting in October 2022 supported by the French army (DGA AID).

How to determine the reference rate of shearing and rate sensitivity for power-law rate dependent crystal plasticity formulation?

In single crystal plasticity, the material strain hardening is specified by the slip system strain hardness which is determined from the strain hardness function (Eqn 1, see attached). Its parameters can be determined by fitting the equation to the experimental stress-strain curve.
