Infos

Kinetic View of Dynamic Plasticity and Fracture of Polycrystalline Solids analyzes kinetic models that can be immediately implemented into simulations of a wide-range of mechanical processes, incorporating dislocation plasticity, deformation twinning, phase transitions, dynamic recrystallization, pore growth, and multiple cracking. The first section provides a state-of-the-art review of kinetic structural models of plasticity and fracture, with the second section outlining novel fully discrete formulations of the kinetic models with the variables defined on the elements of polytopal cell complexes instead of the conventional continuous manifolds.

Finally, the third section discusses the implications of formulations for mechanical criteria of plasticity and fracture, the corresponding rheological models for high-strain-rate material deformation, and finite element method-based simulation results. Users will find guidance on, and examples of, the modeling of deformation processes of nano-sized samples with naturally high strain rates as well as how to use data acquired in microstructural characterization (such as SEM or X-ray).

Autor

Dr. Elijah Borodin has an extensive track record in computational materials science, materials physics, and mechanics. To date, he has published more than 50 papers developing theoretical kinetic approaches to plasticity and fracture of metals subjected to high strain rates, extreme deformation conditions and severe plastic deformations. He had a particular contribution to the mechanical behaviour of fine-grained and nanocrystalline metals where the micro-mechanisms change, and material behaviour often becomes unpredictable. His unique multidisciplinary background allows him to link traditionally well-separated areas of a material’s microstructure evolution and the mechanical behaviour of materials. Dr Borodin has been collaborating extensively with both co-authors of this book. With Prof Mayer they developed theoretical and computational kinetic approaches for continuous formulation of plasticity and fracture processes, while during the last several years, more traditional continuous approaches were supplemented by the novel wholly discrete representation of polycrystalline material microstructures and kinetic processes of its development in close collaboration with Prof Jivkov. Such a combination of multidisciplinary expertise and extensive research in both continuous and discrete formulations provides a unique blend allowing the creation of a holistic picture of the defect structure evolution simultaneously on multiple scales presented in this book. Prof Andrey Jivkov is a recognized expert in solid mechanics and EPSRC Research Fellow (2017-2022). He has authored over 140 peer-reviewed publications, including more than 80 articles in leading journals in the areas of mechanics and physics of materials. He has pioneered mesoscale modelling of deformation and fracture of metallic and quasi-brittle, materials with continuous and discrete mathematical formulations. Prof. Alexander Mayer is a recognized expert in plasticity, damage, and numerical simulations of structural transformation in metals. He has published over 140 publications with a particular focus on shock waves and dynamic deformation of metals, molecular dynamics simulations, and micromechanical models of plasticity and fracture. In the last several years, Prof Mayer and his research group are actively developing multiscale simulations and machine-learning-based approaches.
