ESRD’s software products and consulting services provide crucial support to a variety of aerospace and defense systems, enabling contractors and engineers with the tools, strategies and methodologies required to perform engineering simulations that are Simple, Accurate, Fast, Efficient and Reliable (S.A.F.E.R.) for the occasional user as well as the expert.
Aerospace and Defense System Support
In the Aerospace & Defense application demo shown below, ESRD and our partner Altair collaborated on a global-local workflow for an aero wing flap hinge fitting detailed stress analysis (model and input data courtesy of Altair).
Here are a few of the aviation, aerospace, and defense programs to which ESRD has contributed our simulation software, engineering consulting, or research & development expertise.

“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.”
