StressCheck Use Case: Aerospace
Aerospace application example of how to apply StressCheck to compute maximum first principal stress in the area of airplane wing attachments.
ESRD creates and markets software tools for the advancement of simulation governance in mechanical, aerospace and structural engineering. Motivated by economic incentives, OEMs strive to reduce reliance on physical testing and increase reliance on numerical simulation. To achieve that goal, it is necessary to institute simulation governance which poses new technical requirements. ESRD's flagship product StressCheck is the only FEA product in existence today that was designed to meet the technical requirements of simulation governance. ESRD is a Missouri Corporation founded in 1989.
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.
Detailed stress analysis of 3D joints and complex assemblies through efficient contact
Industry-leading 3D ply-by-ply analysis of laminated composite bonded structures (e.g. Pi joint)
Analyzing stress intensity factors in fractured parts is proven most accurate with StressCheck
Higher-order elements on a single mesh lead to verifiable stresses for complex machined parts
Accurate computation of fatigue-critical stress concentrations, such as in this aerospace assembly
StressCheck checks the stress for convergence ensuring guaranteed reliability
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”.
