Development of an SPH-Enhanced multi-scale FE Framework
This dissertation project explores a novel approach to improve the accuracy and efficiency of simulations in solid mechanics, specifically in the field of powder compaction processes within powder metallurgy and materials science. It integrates Smooth Particle Hydrodynamics (SPH)[1] within the Direct Finite Element2 method[2], a widely used multi-scale analysis technique, to address the limitations of traditional Finite Element (FE) methods in handling large deformations. By combining the ability of SPH to model large strain scenarios with the advantages of FE2 for simultaneous macro- and micro-scale analyses, this research project aims to develop a comprehensive framework. This integration has the potential to revolutionize the modeling of powder behavior and aid in the development of advanced materials and manufacturing processes.

Powder compaction is a pivotal process in various industries, with significant applications in powder metallurgy and pharmaceuticals. Accurate and efficient simulations of powder compaction behavior are essential for optimizing manufacturing processes and material design. Traditional FE methods, which have been the cornerstone of such simulations, encounter limitations due to the growing computational demands and the increasing complexity of systems. To address these challenges, this research project aims to integrate Smooth Particle Hydrodynamics (SPH) into the Direct FE2 method, opening up new avenues for precision and adaptability in numerical simulations.
This student project focuses on the integration of Smooth Particle Hydrodynamics (SPH) into an existing Direct FE2 framework to improve the accuracy and efficiency of powder compaction simulations. The goal is to develop a novel multi-scale method that can address the simulations of complex processes like powder compaction in additive manufacturing. Through rigorous testing and validation, we aim to gain valuable insights into powder behaviors in various materials and structures, ultimately contributing to advancements in various industries.
