The evaluation of damage generated in solids located in radiative media is a major challenge in many technological domains connected to electronic, space, and nuclear industries. The development of nuclear reactor structural materials is the most important part of the effort leading to improve a reliable, environmentally safe, and more efficient nuclear energy production system.
The aim of the project consists of developing a physically based, multiscale constitutive model of irradiated materials. The effect of irradiation on the mechanical properties of metals subjected to various mechanical loading and temperature conditions will be analysed.
The research will be carried out within two major parts comprising the experiments and constitutive modelling of radiation induced damage mechanisms. The simulation of irradiation effects in structural materials using ion irradiation will be performed. The scanning transmission electron microscopy (TEM) will be used to identify radiation defects. The irradiated layers will be analysed by the nanoindentation technique in order to measure the mechanical properties.
The constitutive multiscale model for irradiated solid materials will be developed in the framework of multiscale description and will take into account the relations between all the parameters and the state functions at the micro-, meso-, and macroscopic levels. At the atomic scale, processes occurring in irradiated materials during a displacement phase of the collision will be studied by molecular dynamics (MD) simulations.
At the meso- and macroscopic levels, a novel material model based on nonlocal peridynamic theory will be proposed. Peridynamic theory is a powerful tool for the modelling of materials involving discontinuities.
PhD student's tasks:
Active participation in research carried out in the project, including participation in the development of numerical codes and performing molecular dynamic (MD) simulations and peridynamic (PD) simulations; participation in an analysis of results of different experimental techniques; publication and presentation of results at scientific conferences.
The work will be performed under the supervision of the project manager.
