AFRL CAI Success Story
Abstract: The two directorates, Boeing, Lockheed Martin, Northrop Grumman, and Bell Helicopter make up the CAI team. The team developed and enhanced finite element software for analysis of composite structures. The StressCheck analysis tool shows a significant improvement in bonded and co-cured joint strength prediction capabilities compared to finite element analysis tools currently on the market.

When performing parametric structural analysis, ESRD’s p-element StressCheck® FEA software is always my preferred choice due to the excellent solution quality, parametric framework, and superior computational efficiency. In fact, I recently used StressCheck® to generate stress intensity factors along a parametrically defined elliptical crack-tip across 3,000 unique geometric configurations. Considering multi-body contact was present and all simulations were performed using a laptop, this was a task well suited for StressCheck®.
