A new manufacturing process for biocomposite sandwich parts using a myceliated core, natural reinforcement and infused bioresin
Jiang, Lai (Rensselaer Polytechnic Institute, Troy, NY, 2015-12)Key aspects, process parameter effects and sensitivities and design models of the seven manufacturing steps were investigated and developed further. It was determined that the number of reinforcement plies should be ... -
Acoustic emission-based monitoring of manufacturing processes involving biomaterials
Mishra, Roshan (Rensselaer Polytechnic Institute, Troy, NY, 2020-08)Next, shear-based cutting of bovine bone is studied using single-tooth bone sawing experiments. More specifically, efforts are undertaken to model the acoustic emission signal power, as a function of the specific cortical ... -
Data-driven control of laser powder bed fusion
Shkoruta, Aleksandr (Rensselaer Polytechnic Institute, Troy, NY, 2021-08)There is growing attention to additive manufacturing (AM) processes in industry and academia. Specifically, one metal AM process - laser powder bed fusion (LPBF) - is particularly attractive as it can directly produce ... -
Evaluation of micro-drilling technologies for metal injection molded 420 stainless steel
Silverman, David Elion (Rensselaer Polytechnic Institute, Troy, NY, 2015-08)Metal injection molded (MIM) 420 stainless steel is a commonly used material for high-value products such as fuel injector nozzles. However, the trade-offs involved in using different micro-drilling processes on this ... -
Modeling micro-droplet formation in near-field electrohydrodynamic jet printing
Popell, George Colin (Rensselaer Polytechnic Institute, Troy, NY, 2013-08)Near-field electrohydrodynamic jet (E-jet) printing has recently gained significant interest within the manufacturing research community because of its ability to produce micro/sub-micron-scale droplets using a wide variety ... -
Modeling the ultrasonic sealing process for PEM fuel cell MEAs using a numeric solver and scale-up to 140 cm2
Guglielmo, David (Rensselaer Polytechnic Institute, Troy, NY, 2012-12) -
MRI classification of cartilage degradation
Fleck, Allison Kathleen McEntee (Rensselaer Polytechnic Institute, Troy, NY, 2018-12)This research furthers our understanding of the MR evaluation of articular cartilage and reveals the necessity of considering zonal-dependent properties of articular cartilage. Furthermore, combining zonal analyses and ... -
The cooling and lubrication performance of graphene platelets in micro-machining environments
Chu, Bryan (Rensselaer Polytechnic Institute, Troy, NY, 2016-05)The research presented in this thesis is aimed at investigating the use of graphene platelets (GPL) to address the challenges of excessive tool wear, reduced part quality, and high specific power consumption encountered ... -
The wetting of two dimensional nanomaterials and their industrial applications
Singh, Eklavya (Rensselaer Polytechnic Institute, Troy, NY, 2014-12)Two dimensional atomic crystals such as graphene and transition metal dichalcogenides (TMD's), when synthesized or exfoliated from their layered counterparts, have been shown to possess unique nanoscale attributes. Ballistic ... -
Ultrasonic bonding of membrane electrode assemblies for low temperature proton exchange membrane fuel cells
Beck, Joseph (Rensselaer Polytechnic Institute, Troy, NY, 2012-12)
