Most mechanical properties of crystalline materials are determined by the characteristics of their lattice defects, their mutual interactions, and their collective dynamics. Distinguished Professor Nasr Ghoniem dedicated his career to the field of the mechanics and physics of defects in crystals, with his major contributions focused upon the development of multiscale computational methods for plasticity and damage of materials. Among the numerous achievements of his illustrious career, he is recognized as one of the pioneers in the formulation and development of the discrete Dislocation Dynamics method. In occasion of Professor Nasr Ghoniem’s retirement, this symposium aims to honor his career contributions and foster the advancements in the mechanics and physics of crystal defects, by bringing together the international community of modelers and experimentalists in this field.

Topics of interest include but are not limited to:
• Discrete Dislocation Dynamics and Molecular Dynamics simulations of plasticity and related phenomena
• Modeling of radiation interaction with materials and damage evolution
• Continuum plasticity, phase field and other mesoscale simulation methods
• Ab-initio investigations of defect energetics and their relationships to mechanical properties
• Interaction mechanisms among point defects, dislocations, grain boundaries and material interfaces
• Novel computational methods and numerical techniques in the mechanics and multiscale modeling of crystal defects
• Advanced analysis methods for the convergence and consistency of multiscale modeling problems
• Mechanics and physics of defects in high-temperature and/or irradiated materials
• Statistical aspects of defects microstructure evolution, self-organization and pattern formation
• Novel experimental investigations and characterization techniques of defects in crystalline materials

Papers presented to the symposium will be collected in a special issue of Materials Theory.
