“StressCheck®’s quality control features have given us the tool we need to perform detailed … bonded joint analysis with confidence that the results are accurate.” “… StressCheck® has greatly improved our ability to accurately predict the fatigue life of joints with interference fit fasteners and cold worked holes” – The Boeing Company
“This software tool … includes an FEM-based handbook format which allows non-experts to utilize models prepared by specialists.” — Lockheed Martin
What is StressCheck?
StressCheck® is a comprehensive 64-bit finite element analysis software (FEA) tool with a fully integrated pre- and post-processor and a suite of analysis modules that support advanced engineering computations in the applications of solid mechanics.
StressCheck has utility modules that offer functionality to import NASTRAN bulk data format, to import CAD models and to perform 2D and 3D automatic meshing. StressCheck provides industry-leading post processing options which include error estimators for the assessment of the quality of approximation: Global error estimation in energy norm and local error estimators for any data of engineering interest.
StressCheck is based on the p-version finite element method, which is explained under Our Technology. Because the p-version is a more comprehensive implementation of the finite element method than the h-version, StressCheck can be operated in both the “h-mode” (least efficient) and “hp-mode” (most efficient).
StressCheck® has a broad range of industrial applications, including but not limited to:
- fatigue and fracture
- residual stress
- crack growth support
- damage tolerance assessment
- fastened and bonded joints
- laminated composite analysis
- detailed stress analysis
- vibration and buckling analysis
Key Features and Benefits
Allows for elements with very large aspect ratios (200:1 or larger) which is essential for the ply-by-ply modeling of laminate composites and bonded composite joints.
Makes it possible for the elements to accurately represent the shape of the part which is extremely valuable for accurate stress analysis of single parts and for multi-body contact situations such as multi-fastened joints.
Allows for a nonlinear analysis to be continued from a linear analysis, or to switch from linear elastic to buckling.
From global models are available for global-local stress analysis.
Allows analysts to extract any data from the FE solution and assess the convergence of the results. Results are not limited to nodes, as the solution is available everywhere in the model (mesh-independent).
For deployment of standard solutions with confirmation of reliability. This allows users the ability to create a library of parametric models to serve as repository for standardization and corporate design knowledge. FE-based handbook solutions eliminate the need of overly simplified assumptions typical of closed-form solutions found in classical handbooks, and can be customized to accurately describe real world problems.
Via highly reliable and efficient procedures: Stress intensity factors for through and corner cracks in isotropic materials and energy release rate components for cracks and delamination in composite materials.

“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.”
