Plastic heterogeneities characterisation in 16MND5 RPV steel by X-Ray diffraction, comparison with Finite-Elements approach
This paper reports experimental characterisation of stress heterogeneities in a French RPV bainitic steel (16MND5) determined by X-Ray diffraction during in-situ tensile testing at low temperature (until -150 degrees C). Results are compared successfully to simulation results, obtained by post-processing of Finite Elements computations of realistic 3D aggregates.
