The capabilities available with BAMF, AFGROW and StressCheck^® are highly advanced and offer significant potential to achieve the high-level goal of TITANS –to reduce the need to conduct expensive and time consuming physical tests and to rely more on simulation.

The software provides a highly reliable and user-friendly production stress analysis tool that will replace the Finite Element Method (FEM) tools and failure criteria the experts currently employ for analyzing bonded joints. The software includes an FEM-based handbook format, which allows non-experts to utilize models prepared by specialists. The handbook problems include built-in failure criteria, geometric and material nonlinearities, and the modern FEM technology provides better error control and the treatment of very large aspect ratios.”

“A screening of existent commercial and non-commercial tools was carried out in respect to their fracture mechanics capabilities, their design abilities, implementation as well as their complexity. Although, there are many software possibilities, only those within the reach of the author were evaluated. This resulted in the selection of the commercial tool StressCheck^®. The assessment of crack propagation on compact tension and two stringer specimens governed by the Paris and Forman regimes was satisfactory compared with experimental results using the material data from simple standard specimens.”

“In the case of the through crack configuration, the comparison of experimental and StressCheck^® derived geometry factors showed a close correlation and were an improvement to solutions provided in AFGROW at the time. Based on the results of this research, StressCheck^® pin-loaded lug geometry factors have since been incorporated into the AFGROW software.”

“We have found StressCheck^® very useful for computational fracture mechanics for both metallic and composite components. In recent years it has been extensively used in determining beta factors for RAAF’s C-130 Wing DTA locations and associated generic research.”

“StressCheck^® is the work horse for NAVAIR Structures’ detailed stress and stress concentration calculations. This software also is the basis for our development of a Structural Analysis Management System.”

“Through the use of StressCheck^® the A-10 Aircraft Structural Integrity Program’s (ASIP) Analysis Group is able to model more accurately the physics of fatigue crack propagation in critical aircraft structure.  Through this tool we are able to model, analyze and predict failure of aircraft structure and then develop crucial inspection and maintenance planes to ensure the safety and sustainability of our nations warplanes.  Without the analysis capability provided to us through StressCheck^® we would not be able to provide accurate assessments of the A-10 structure to top USAF leadership.”

“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.”
