ESRD, Inc. is the developer of StressCheck®, the world’s premier high definition, detailed analysis simulation tool, and are thought leaders in Simulation Governance, the deployment of Smart Engineering Simulation Apps and the Democratization of Simulation.
We have dedicated our professional careers to delivering reliability.
Engineering Software Research and Development, Inc. (ESRD) is a Missouri Corporation founded in 1989 by Dr. Barna Szabo, Mr. Kent Myers, and Dr. Ivo Babuska. ESRD is engaged in the development of advanced engineering software products and offers professional services in areas pertaining to numerical simulation in the fields of mechanical, aerospace and structural engineering.
ESRD’s flagship software product, StressCheck® Professional, is an advanced FEA tool having numerous unique technical capabilities. It is the first and so far only FEA software product designed to support Simulation Governance.
Our Mission and Vision
Our mission is to create and market software tools for the advancement of the quality, reliability and timeliness of information that serves the engineering decision-making process.
ESRD was first to recommend the establishment of simulation governance and simulation management practices and continues to provide leadership in this emerging area.
The full potential of numerical simulation technology is yet to be realized. Properly managed, numerical simulation is an important corporate asset but poorly managed, or not managed at all, it can become a major corporate liability.
Numerical simulation tools should be made simple, accurate, fast, efficient and reliable (S.A.F.E.R.) not just for expert structural analysts, but also for engineers whose expertise is not in numerical simulation.
The S.A.F.E.R. Simulation Approach
The founders believe that the key challenge for providers of engineering software is to improve the reliability of information generated by mathematical models while substantially reducing the time required for performing computer-aided design and analysis tasks. This means no shortcuts, tricks, or “Finite Element Modeling“. Only S.A.F.E.R., Finite Element-Based Numerical Simulation.
The principals of ESRD have been performing research and development related to finite element analysis for more than 30 years. The knowledge base implemented in StressCheck® Professional has been thoroughly documented in peer-reviewed professional journals and textbooks.
ESRD has undertaken numerous directed development contracts from industry OEM’s to enhance StressCheck® Professional to suit specific technical requirements and to develop customized engineering applications that utilize the StressCheck® Professional API to serve the needs of corporate design and analysis tools.
Barna Szabó, Ph.D., P.E.
Co-founder and Chairman of the Board
Prior to his retirement from the School of Engineering and Applied Science of Washington University in 2006, he served as the Albert P. and Blanche Y. Greensfelder Professor of Mechanics. His primary professional interest is assurance of quality and reliability in numerical simulation of structural and mechanical systems by the finite element method. He has published over 150 papers in refereed technical journals, several of them in collaboration with Professor Ivo Babuška, with whom he also published two textbooks on finite element analysis (Wiley, 1991, Wiley 2011). He is a founding member and Fellow of the US Association for Computational Mechanics. Among his honors are election to the Hungarian Academy of Sciences with an honorary doctorate.
Ricardo Actis, D.Sc.
President and Chief Executive Officer
Dr. Ricardo Actis received his D.Sc. degree in Mechanical Engineering from Washington University in St. Louis in 1991. He joined ESRD shortly after graduation as the senior engineer and later director of engineering development, position which he held until 2008 when he was appointed vice-president. In 2011 Dr. Actis became CEO of the company, and the role of President and CEO in 2016. During his years at ESRD, Dr. Actis had direct responsibilities for the implementation of advanced FEA procedures, including material and geometric nonlinearities, thin solids formulation, plates and shells, multi-body contact, composite material analysis techniques, post-processing procedures, including the extraction of fracture mechanics parameters for metallic and composite structures. He is currently responsible for managing the formulation and implementation of engineering functionality within the infrastructure of the finite element analysis software product StressCheck®. Since 1994 Dr. Actis also serves as an adjunct professor at the School of Engineering and Applied Science in the Department of Mechanical Engineering and Materials Sciences at Washington University in St. Louis, teaching in the areas of strength of materials, aircraft structures, and finite element analysis.
Sebastian Nervi, D.Sc.
Dr. Sebastian Nervi received his D.Sc. degree in Mechanical Engineering from Washington University in St. Louis in 2005. Prior to receiving his degree, he joined ESRD that year as the Senior Staff Engineer. He was later promoted to Director of Engineering Development, a position which he held from 2008 to 2012. In 2012, Dr. Nervi became a contract engineer for the Boeing Company and in 2015 rejoined ESRD as the Product Manager, overseeing the life cycle of all ESRD software. During his years at ESRD, Dr. Nervi has had direct responsibilities for the coordination and management of the engineering team in engineering consulting services for the mechanical and aerospace industry, as well as management of the research and development team for implementation and enhancement of new functionalities on ESRD’s finite element analysis product StressCheck®. He has also been in charge of development of new functionalities, enhancement of existing capabilities, testing and documentation of commercial finite element analysis products, applications in non-linear continuum mechanics, residual stresses and fracture mechanics. Currently Dr. Nervi is in charge of ensuring solid product management, from inception to the market.
Matt Watkins, PE
Mr. Matt Watkins joined ESRD in 2009 as an Application Engineer. He holds a M.S. degree in Aerospace Engineering from Washington University in St. Louis, where he currently teaches finite element analysis as an adjunct instructor in the School of Engineering and Applied Science. In 2016, he received his Missouri Professional Engineering (PE) license and was promoted to Engineering Project Manager. In this role, he coordinates and leads the ESRD engineering services team in funded projects and research in the areas of fracture mechanics, residual stress, distortion, and the development of simplified software tools which allow non-experts to use advanced analysis methods in safe and reliable frameworks. The technically challenging environment at ESRD has provided a great opportunity for him to combine his engineering experience with his long-time enjoyment of programming complex software.

Recent News & Events
“At DST Group, we have effectively used StressCheck® over the last 10 years to determine accurate stress intensity factors. The results have been used to improve our residual strength and structural life estimates for aircraft in service with the Royal Australian Airforce, including C-130, P-3C and F/A-18 A/B. We have found it to be extremely easy to use and a very versatile code with which to create parametric models.
We have recently used StressCheck® to obtain improved stress intensity factor solutions (Improved stress intensity factors for selected configurations in cracked plates and Improved stress intensity factors for a single corner crack at a loaded fastener hole) for five key generic configurations. These transferable parametric results have been published externally. One specific example is the non-linear contact analysis of a cracked, filled fastener hole, with both fastener and remote plate loading.”
