Ultrasonic Nondestructive Evaluation Of Metal Additive Manufacturing., Venkata Karthik Nadimpalli May 2018

Ultrasonic Nondestructive Evaluation Of Metal Additive Manufacturing., Venkata Karthik Nadimpalli

Electronic Theses and Dissertations

Metal Additive Manufacturing (AM) is increasingly being used to make functional components. One of the barriers for AM components to become mainstream is the difficulty to certify them. AM components can have widely different properties based on process parameters. Improving an AM processes requires an understanding of process-structure-property correlations, which can be gathered in-situ and post-process through nondestructive and destructive methods. In this study, two metal AM processes were studied, the first is Ultrasonic Additive Manufacturing (UAM) and the second is Laser Powder Bed Fusion (L-PBF). The typical problems with UAM components are inter-layer and inter-track defects. To improve the …

Manufacturing Process Simulation – On Its Way To Industrial Application, Dennis Otten, Tobias A. Weber, Jan-Christoph Arent

International Journal of Aviation, Aeronautics, and Aerospace

Manufacturing process simulation (MPS) has become more and more important for aviation and the automobile industry. A highly competitive market requires the use of high performance metals and composite materials in combination with reduced manufacturing cost and time as well as a minimization of the time to market for a new product. However, the use of such materials is expensive and requires sophisticated manufacturing processes. An experience based process and tooling design followed by a lengthy trial-and-error optimization is just not contemporary anymore. Instead, a tooling design process aided by simulation is used more often. This paper provides an overview …

Sensel Morph: Product Communication Improvement Initiative, Kasper W. Lui-Delange, Samuel Distler, Rafael Paroli Mar 2018

Sensel Morph: Product Communication Improvement Initiative, Kasper W. Lui-Delange, Samuel Distler, Rafael Paroli

Industrial and Manufacturing Engineering

Sensel is a startup company that recently launched their first product. The Morph is a multi-functional touch interface that interacts with a wide range of software through touching enabled silicon overlays. The support documentation was believed to cause confusion, which is leading to limited sales and increased returns. We focused on the structures of its website and product documentation, which were initially developed without end user testing. Our team explored Sensel’s current state to develop two multiphase design alternatives. These designs provide multiple user-facing testing frameworks as well as determine the root-cause of the Morph’s current communication issues. The designs …
