Kinetic View of Dynamic Plasticity and Fracture of Polycrystalline Solids

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).
