Institute of Virtual ManufacturingOpen OpportunitiesMeeting the demands of evolving manufacturing and environmental landscapes frequently entails the development of pioneering processes and materials. Yet, generating innovative materials presents its own set of challenges. This project necessitates the establishment of a methodology for producing rods and wires, facilitating the production of powder for novel alloys. To accomplish this task, a forging machine known as a round swage will be employed. The created rods and wires will be used to produce powder using Ultrasonic Plasma Atomizer (UPA) and the wires will be used as is for Directed Energy Deposition (DED), an additive manufacturing technology. - Alloy Materials, Composite Materials, Manufacturing Engineering

| The Advanced Manufacturing Lab (am|z) is excited to announce a thesis opportunity focusing on the development of a highly parallelizable modeling framework for additive manufacturing (AM) processes, particularly laser powder bed fusion (LPBF). Our research primarily delves into advancing manufacturing techniques, with a special emphasis on additive manufacturing. We have developed a robust numerical simulation framework called iMFREE utilizing Smoothed Particle Hydrodynamics (SPH) for multi-physics applications like LPBF. However, there is a need to enhance computational efficiency, specifically through parallelization via Message Passing Interface (MPI). This project offers an excellent chance for students to deepen their knowledge in parallel computation while working hands-on with a mature computational framework. - Engineering and Technology, Information, Computing and Communication Sciences

| The Advanced Manufacturing Lab (am|z) is a leading hub for innovative research in advanced manufacturing and materials processing technologies, with a particular focus on advancing 3D printing processes in metals and polymers. The goal of this thesis project is to develop a numerical model for the Fused Deposition Modeling (FDM) 3D printing process. The model will be developed using the commercial finite element solver COMSOL Multiphysics. To ensure its accuracy, the numerical model will be validated against existing experimental data. - Manufacturing Engineering, Materials Engineering

| 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. - Manufacturing Engineering, Materials Engineering, Mechanical and Industrial Engineering

| A numerical model of the SPS process requires the solution of the involved multi-physics partial differential equations with mixed boundary conditions. For a good predictive numerical model, the material model plays a pivotal role and some constitutive laws, e.g., Olevsky’s and Abouf’s models, are already available in the literature; however, these existing models are lacking a systematic approach for their parameter identification with experimental validation. In this project, we would
like to resolve this issue by utilizing an efficient and fully coupled electro-thermo-mechanical FEM model in the commercial package COMSOL Multiphysics. - Manufacturing Engineering, Materials Engineering, Mechanical and Industrial Engineering
