COVID-19 Response and Call for Papers
Although the journal is committing to reviewing and processing papers as expeditiously as possible, we understand that members of our community including editors, authors, and reviewers may be impacted severely by the pandemic. If you are experiencing any difficulties with journal related workflow we encourage you to communicate with the journal Editor or Associate Editor(s) so that accommodations and/or time extensions can be arranged.
To assist researchers and those working to bring this health crisis to an end, ASME has made all COVID-19 relevant journal and conference content available at no charge. We encourage JMD authors to contribute articles to COVID-19 related subjects. Such papers will still be submitted to JMD, going through an expedited review process, and published with a link to the ASME COVID-19 Resource virtual issue at https://asmedigitalcollection.asme.org/journals/pages/covid19resource

Efficient Spot Welding Sequence Optimization in a Geometry Assurance Digital Twin
Roham Sadeghi Tabar, Kristina Wärmefjord, Rikard Söderberg, Lars Lindkvist
The availability of big data has made the role of digital twins in manufacturing more prominent. This paper introduces a geometry assurance digital twin - created from the scanned data of individual components - to define and improve an assembly’s geometrical quality. The joining sequence in a sheet metal assembly impacts geometrical quality and determining the optimal joining sequence is computationally expensive. Meta-heuristic optimization techniques like genetic algorithms often require many simulations, which can increase computational cost. This work improves the optimization process by combining a model-based heuristic algorithm...read more
Conceptualizing Stable States in Origami-Based Devices Using an Energy Visualization Approach
Jacob Greenwood, Alex Avila, Larry Howell, Spencer Magleby
Origami can provide unique inspiration when designing engineered systems because it promotes multiple configurations, compact storage, and quick deployablility. However, origami-based products can be challenging to design because they often are mechanically unstable - folding when not desired or when under load. While there are some existing techniques for achieving stability in origami-based designs, determining which combination of techniques will achieve the desired results for a given application can be difficult. For example, how can you design an origami-based ballistic barrier to stay upright when you need it for protection, but also stay collapsed for storage? Read more...
Evaluating the Use of Virtual Reality to Teach Introductory Concepts of Additive Manufacturing
John K. Ostrander, Conrad S. Tucker, Timothy W. Simpson, Nicholas A. Meisel
Additive manufacturing (AM) is becoming more prevalent in the classroom. Most AM education, though, is limited to desktop-scale material extrusion printers since they are relatively safe, easy to use, and inexpensive. However, industry demand continues to rise for students skilled in more advanced forms of AM, such as laser-based, metal powder bed fusion. Unfortunately, the cost, infrastructure, and training necessary for using these complex systems in education present challenges for classroom implementation. This research proposes using virtual reality (VR) as a medium for teaching introductory concepts of AM without the need for a physical printing system located in the classroom. Read more...
