In mid-May 2023, ESRD’s Co-Founder and Chairman Dr. Barna Szabó will deliver a keynote presentation at the ASME VVUQ 2023 Symposium in Baltimore, Maryland, USA. Dr. Szabó’s presentation, entitled “Simulation Governance: An Idea Whose Time Has Come”, will focus on the goals and means of Simulation Governance with reference to mechanical/aerospace engineering practice.
The abstract of the keynote presentation is as follows:
Mathematical models have become indispensable sources of information on which technical and business decisions are based. It is therefore vitally important for decision-makers to know whether or not they should rely on the predictions of a particular mathematical model.
The presentation will focus on the reliability of information generated by mathematical models. Reliability is ensured through proper application of the procedures of verification, validation and uncertainty quantification. Examples will be presented.
It will be shown that mathematical models are products of open-ended evolutionary processes. One of the key objectives of simulation governance is to establish and maintain a hospitable environment for the evolutionary development of mathematical models. A very substantial unrealized potential exists in numerical simulation technology. It is the responsibility of management to establish conditions that will make realization of that potential possible.
In late February 2021, ESRD's CAE Handbook was officially added to the Altair Partner Alliance (APA). CAE Handbook provides an elegant and intuitive framework for deploying StressCheck-powered digital handbook solutions.
With the release of StressCheck v11.1, we have made tremendous improvements to model rendering, load arrow drawing and load record updating performances to provide the user with maximum efficiency. This release also provides new mixed element meshing functionality in the Crack Front and Boundary Layer methods as well as the all-new Thin Section method, which allow the user to utilize pentahedral and hexahedral elements together with a traditional all-tetrahedral automesh. These improved, high-quality meshes can provide the user more accurate results with less computational cost, especially for fracture and contact problems.
StressCheck v11.1 also boasts improvements for Global-Local analysis in the form of TLAP scaling parameters and improved GUI options for point load/constraint rendering, as well as updates to the COM API functionality and the StressCheck Offline Documentation.
From all of us at ESRD, we wish you a very happy holiday season! We truly feel that each and every one of our users are part of the ESRD family and we are incredibly grateful to get to work with all of you.
There is much we are thankful for as we approach the end of the year, and we'd like to take a moment to acknowledge some of the reasons we're looking back fondly on 2023...
“The addition of incremental theory of plasticity in StressCheck has greatly improved our ability to accurately predict the fatigue life of joints with interference fit fasteners and cold worked holes. This ability is especially important, not only in support of maintaining aging aircraft but also in analyzing some of the new cold working techniques that have been introduced in recent years.
Prior to this implementation, analysts often relied on closed-form approximations or simple factors that were often overly conservative and sometimes even unconservative when used in life prediction. Now, not only can we more accurately predict residual stresses in these complex structural joints, but we can also do so in a timely manner given the modeling and analysis efficiency that exists with a p-version FEA code such as StressCheck.”
