What is StressCheck?
StressCheck is a comprehensive finite element analysis software tool with a pre and post-processor and a suite of analysis modules that support advanced solution methods in linear elasticity, multi-body contact, geometric and material nonlinearities, modal and buckling analysis, fracture mechanics, laminate composite analysis, and steady state heat transfer, including temperature-dependent material properties and radiation.
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”.
Key Features & Benefits
The robust element formulation in StressCheck 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. Several 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.
Additionally, StressCheck provides a Handbook framework for deployment of standard solutions with confirmation of reliability. Users can 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. Highly reliable and efficient procedures for the extraction of fracture mechanics parameters is available in StressCheck: Stress intensity factors for through and corner cracks in isotropic materials and energy release rate components for crack and delamination in composite materials.
Industrial applications are targeted at aerospace engineers with key focus on fatigue and fracture, crack growth, damage tolerance assessment, fastened and bonded joints and laminated composite analysis. StressCheck is ideally suited to support processes which are variously called “building block method”, “validation pyramid” and “validation hierarchy”.
StressCheck is available on 32-bit or 64-bit Windows XP (SP2 or later) and Windows 7 operating system as a 32-bit application. Other Windows operating systems may operate satisfactorily, but those operating systems are not explicitly supported. Floating licenses require Window XP, Windows 7 or Windows Server 2003 as the license server operating system to run FLEXnet License Server.
