We developed the world’s premier high-order FEA tool, StressCheck® Professional, to empower our customers to obtain reliable solutions to their challenging engineering applications.
What kinds of engineering applications are on your mind today?
Are high-resolution stress or strain gradients important to you? Or, any of the following?:
- Stress concentrations for small and/or difficult to analyze features
- Adhesively bonded ply by ply laminated composites details
- 3D stress intensity factors for user-defined crack geometries
- Multi-body contact analyses of fastened joints
- Residual stress due to cold-working process
- Global-local analysis of airframe details
- Customized engineering simulation apps

“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.”
