Best Practices for Engineering Calculations- Calculate, Document, and Share

Calculations are at the heart of engineering and vital to the success of projects, product design, and ultimately the success of a company. It is essential to capture calculations in a way that is easy to reuse and share with others. This allows you to spend more time finding solutions and less time documenting them.

Heat Transfer Simulations

Heat transfer is central to many simulations – as a direct, desired effect or a byproduct to be managed. This webinar will examine how heat transfer couples with other physics. We’ll start with convection and structural thermal expansion and move on to electromagnetic, chemical, and acoustic heating. We will conclude with a worked example that demonstrates how easy it is to solve this class of problem with COMSOL Multiphysics.

Marcia Domack and John Wagner, Engineers, NASA Langley Research Center, Hampton, VA

Marcia Domack and John Wagner, engineers in the Advanced Materials and Processing Branch at NASA Langley Research Center, have worked with Boston-based metal fabricator Spincraft, focusing on a one-piece manufacturing process called spin forming. The team used the spin-forming technique to create a model of the forward pressure vessel bulkhead (FPVBH) of an Orion-type crew module.

Stephen Freeman, Vice President of International Business Development, Materion Corporation

Recently, NASA Tech Briefs spoke with Stephen Freeman, Vice President of International Business Development for Materion Corporation, which is the new name for advanced materials manufacturer Brush Engineered Materials and all of its businesses. Materion is a New York Stock Exchange listed company with annual sales of 1.5 billion dollars. A 20-year veteran of Materion, Steve discusses how the rollout of the new Materion brand has progressed over the past year, new and exciting applications for beryllium and their other materials, and how they also have developed into the world’s largest optical coatings manufacturer.

Sandeep Yayathi, Robotics Engineer, NASA Johnson Space Center, Houston, TX

The Robonaut is a humanoid robot, so it’s a robot that looks very much like a person. It has two arms, similar degrees of freedom, and some complex dexterous hands. The hands are also very similar to what we have on our arms. The goal is for the Robonaut to be able to interface with the same interfaces that the crew uses now, and be able to handle the same tools that they use in orbit. Currently we have an (intra-vehicular activity) IVA version of the Robonaut, so it’s inside the space station mounted to a stanchion that the crew’s been working with. Looking forward to the future, we are currently working on a battery-based power system, as well as a pair of legs. Not so much legs like you and I have, but similar to the arms, with specialized end effectors for grabbing on to fixtures, tracks, and hand rails available on the station. This will set the stage for eventually having a robot that goes EVA [extra-vehicular activity].

Stephen Merkowitz, Project Manager, NASA Goddard Space Flight Center, Greenbelt, Maryland

Stephen Merkowitz: NASA currently offers a network of space geodetic ground stations that do Very Long Baseline Interferometry (VLBI), satellite laser ranging (SLR), and [global navigation satellite system] GNSS or GPS tracking. The new space geodesy project will develop and implement the next-generation systems. The current systems are 20-30 years old. One of the primary drivers for upgrading the system is sea-level measurement, where you would like to be able to make those measurements at the millimeter level and have them be stable over the years, so you can do repeated measurements.
