Product Snapshot

StressCheck® Professional is a comprehensive Windows 10-compatible, 64-bit finite element analysis software (FEA) tool with a fully integrated pre- and post-processor (StressCheck® Core) and a suite of solver and analysis modules that support advanced engineering computations in applications of solid mechanics. Productivity tools are available to import NASTRAN bulk data file meshes and CAD geometry, perform 2D and 3D automatic meshing, automate analyses via Developer’s API, and more.

StressCheck® Professional provides industry-leading live dynamic results processing options which include error estimators for the assessment of the quality of model approximation: global error estimation in energy norm and local error estimators for any engineering function of interest. Additionally, live extractions of stresses, strains and even combinations of engineering functions can be made anywhere in the model, at any time, at any resolution.

What does this all mean? Users need not spend excess time on meshing the model according to traditional FEA schema or planning ahead for myriad post-processing needs; StressCheck®‘s implementation provides the flexibility to account for changing requirements in engineering analysis results, all within the same model and mesh.

Solvers

StressCheck® Professional supports a wide variety of solvers, including linear, multi-body contact, nonlinear (material and large deformation), modal/buckling, steady state heat transfer, and more.

Learn More

Advanced Modules

StressCheck® Professional has advanced modeling capabilities in the areas of composites, fracture, residual stress and more. These are the StressCheck® Advanced Modules, each module independently licensed as add-on modelers. Many of the features in these modules may even be combined together in a single model for more sophisticated FEA needs.

Key Features and Benefits of StressCheck® Professional

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. Elements are not susceptible to shear locking, “hourglassing”, “overstiffening” or other problems that plague FEA users.

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.

Seamless Transition Between Theories...

Allows for a nonlinear analysis to be continued from a linear analysis, or to switch from linear elastic to buckling.

Multiple Methods Of Importing Loads/Displacements...

From global models are available for global-local stress analysis.

Robust and Flexible Post-Processing...

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).

A Unique 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.

Testimonials

  • “The p-type element has been used to great advantage in the finite element system ESRD StressCheck®, [26]. This software provides the engineer with the means to conduct solution verification in an extremely straightforward manner by simply increasing the degree of the element, monitoring convergence and using Richardson extrapolation reliably to estimate the error. This can be conducted automatically by the software thereby enabling the engineer to concentrate on the engineering rather than the simulation. StressCheck® has also been used to develop ESRD’s Handbook and Toolbox applications. The first of these provides engineers with a repository of parameterised standard problems of the type found in texts like Roark’s “Formulas for Stress and Strain”, [27]. The second, Toolbox, is a tool that can be used to parameterise a company’s range of components for rapid and reliable analysis by non-expert analysis. Toolbox then is an exemplary of the way in which the democratisation of simulation can be applied.”
