CRYSTAL PLASTICITY ANALYSIS OF SEVERE PLASTIC DEFORMATION

Advancements in technology for the creation, characterization, modeling, design, and application of nanostructured materials are essential for maintaining competitiveness in the global industrial design and manufacturing market. Recently, processing extremely fine-grained metals through severe plastic deformation (SPD) techniques has reached a critical phase in development. Sufficient laboratory findings are available to demonstrate the overall viability of this approach, and it is widely acknowledged that these materials hold significant innovation potential. The present work aims to conduct numerical investigations into the severe plastic deformation behaviors of metallic materials using both classical continuum and microscale approaches based on finite element analysis. The study provides detailed insights into the mechanical properties and deformation mechanisms of various metals subjected to SPD, highlighting the role of microstructural evolution during processing. Experimental validation of the models is presented, along with a comparison of the different simulation techniques employed. The findings contribute to the understanding of how advanced materials can be effectively processed and utilized in aerospace applications.
