|"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."
StressCheck® is a comprehensive 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:
- linear elasticity
- multi-body contact
- geometric and material nonlinearities
- modal and buckling analysis
- fracture mechanics parameters
- laminate composite analysis
- global-local analysis
- steady state heat transfer (including temperature-dependent material properties and radiation)
- ...and more
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. Because the p-version is a more comprehensive implementation of the finite element method than the h-version, StressCheck® can be operated in the “h-mode”.
StressCheck® has a broad range of industrial applications, including but not limited to:
- fatigue and fracture
- crack growth support
- damage tolerance assessment
- fastened and bonded joints
- laminated composite analysis
- detailed stress analysis
- vibration and buckling analysis
| Key Features & Benefits:
- Robust element formulation 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.
- High-order mapping 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.
- Multiple methods of importing loads/displacements from global models are available for global-local stress analysis.
- A robust and flexible post-processing allows analysts to extract any data from the FE solution and assess the convergence of the results.
- Handbook framework 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.
- Extraction of Fracture Mechanics parameters 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.
