Biography:

Wolfgang Gentzsch is the president and co-founder of the UberCloud Community and Marketplace for engineers and scientists to discover, try, and buy computing on demand, in the cloud. From 2010 to 2015, he was the co-chairman of the International ISC Cloud & Big Data Conference series. Previously, he was Advisor to the EU projects EUDAT and DEISA, directed the 150 Million Euro German D-Grid Initiative, and was a member of the Board of Directors of the Open Grid Forum and of the US President's Council of Advisors for Science and Technology, PCAST. Previously, he was a Professor of Computer Science and Mathematics at several universities in the US and Germany, and held leading positions at the North Carolina Grid and Data Center in Durham, Sun Microsystems in California, the DLR German Aerospace Center in Gottingen, and the Max-Planck-Institute for Plasma physics in Munich. In the 90s, he founded HPC software companies Genias and Gridware. The latter, which has been acquired by Sun Microsystems in 2000, developed the well-known distributed cluster workload and management system Grid Engine.

Abstract:

In recent years new and revolutionary trends in digital manufacturing are overwhelming our community. Design, simulation and prototyping more and more are moving to the cloud, and new areas like big data, predictive analytics, and the Internet of Things are coming up the horizon, accompanied by great promise for increased product quality, reduced product failures, and better predictability for market acceptance and customer use. This talk will touch on all these new trends, and illustrate with one example in more detail the benefits of these new paradigms: Computer Aided Engineering Simulations in the Cloud. Although today still the majority especially of small and medium manufacturers don't perform computer simulations at all or just on their local workstations, there is now a strong trend toward adding more powerful hardware and software to their daily tools. In a sudden, today, engineers can access the whole spectrum of computing, from their workstation to servers to clouds, integrated with feature rich application simulation software for e.g. fluid dynamics, material analysis, multi-physics, and more. In our talk, we will analyse the roadblocks and benefits of these powerful tools and demonstrate how they are currently overcome by new technologies such as application software containers running seamlessly on any computing resource on demand. We will close our talk with several digital manufacturing case studies demonstrating this progress.

Biography:

Omar S Es-Said is a Professor in the Mechanical Engineering Department at Loyola Marymount University in LA, California. He was a full Professor from 1998 to present. He received his PhD in Metallurgical Engineering and Materials Science from the University of Kentucky, Lexington in 1985. His current research interests include metallic processing and modeling. He published over 300 papers. He has been an Associate Editor from 2008 to present for the Journal of Materials Engineering and Performance. He received several grants and awards for research funds for a total of over $3.6 million. He was a consultant for the Navy from 1994-2015 and a fellow of the American Society of Materials in 2005.

Abstract:

Three experiments were performed on the effect of hydrogen charging on the charpy impact toughness of 4340 steel. In the first experiment 4340 steel plates were austentized and tempered to give the following target tensile strength values of: 1000, 1102, 1170, 1240, 1310, 1410, 1515, and 1720 MPa. Charpy impact samples were tempered at each of these temperatures. These samples were separated into uncharged and hydrogen charged samples. The charged samples were then plated with 0.0076 to 0.013 mm thickness layer of cadmium. It was found that samples tempered above 468°C and subjected to hydrogen charging exhibited lower impact energy values when compared to un-charged samples. No significant difference between charged and un-charged samples tempered below 468°C was observed. In a second experiment steel plates were Electro Discharge Machined into twenty-four compact tension fracture toughness bars. These samples were divided into four groups: as-received, tempered, cadmium coated, and cadmium coated and tempered. The cadmium coating was 0.013 mm in thickness. The tempering temperatures were 354°C, 468°C, and 621°C, for two hours. Also, charpy impact samples were treated in the same way. A correlation between the fracture toughness and Charpy Impact values was obtained. In a third experiment tempered 4340 steel was hydrogen charged by cadmium plating of 0.005 mm, 0.0076 mm, and 0.013 mm. It was found that charpy impact energy was highest for the 0.005 mm and lowest for the 0.013 mm across all strength values. The results can be explained by the model of (hydrogen) atmospheres associated with mobile dislocations.
