What is StressCheck®?

  • From the perspective of managers, StressCheck® is the only FEA tool that supports simulation governance.

  • From the perspective of analysts, StressCheck® is the only FEA tool that supports solution verification in practical engineering settings.

  • From the perspective of designers, StressCheck® provides a framework for standardization of routine design procedures with guaranteed reliability.

"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

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”.     

 
 
 
 
Industry Applications:

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.
