WEBINAR SUMMARY
In this webinar we will detail the latest technological advancements for accurate simulation of three-dimensional metallic crack growth via coupled finite element analysis (FEA) and fatigue life computations. Additionally, we will examine why the development of more complex crack growth models requires both tighter control over numerical errors (i.e. solution verification) and rigorous benchmarking to standard handbook solutions and available experimental data (i.e. model validation).
WEBINAR HIGHLIGHTS
This webinar will be jointly presented by ESRD, Hill Engineering, LLC (developers of BAMF) and LexTech, Inc. (developers of AFGROW), and will explore the latest technologies, methodologies and software implementations available for DaDT and fatigue engineers to numerically simulate fatigue crack propagation.
The effects of engineered residual stresses (ERS) on crack shape evolution and the associated cyclic fatigue life will be assessed in several practical case studies.
StressCheck is a comprehensive Windows 10-compatible, 64-bit finite element analysis software (FEA) tool with a fully integrated pre- and post-processor 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 StressCheck‘s API, and more. StressCheck is ideally suited for damage tolerance and forensic engineers who need the best representation of 2D or 3D SIF’s, ERR’s and beta factors for input in sophisticated crack growth simulations, or when analyzing repairs for mitigation of cracks.
AFGROW is a Damage Tolerance Analysis (DTA) framework that allows users to analyze crack initiation, fatigue crack growth, and fracture to predict the life of metallic structures. AFGROW (Air Force Grow), was originally developed by The Air Force Research Laboratory. It is now being developed and maintained by LexTech, Inc. AFGROW is one of the most efficient and widely used crack growth life prediction tools available today. AFGROW is mainly used for aerospace applications; however, it can be applied to any type of metallic structure that experiences fatigue cracking. AFGROW is also a very flexible and user-friendly computer program.
BAMF is used for fatigue analysis, and it is capable of predicting the growth of fatigue cracks in 3D parts. Starting from an assumed initial flaw, BAMF combines stress and crack growth analyses to predict the evolution of crack shape and size in 3D. BAMF provides a robust and automated link between two leading tools: AFGROW and StressCheck. Key features of BAMF include: natural crack shape evolution, fully 3D fatigue analysis capability, complex loading support, multiple cracks, and residual stress compatibility.
Recently at ASIP 2022 in Phoenix, AZ, ESRD provided a 2-hour training course titled “Best Practices for the Modeling and Analysis of Bonded Doubler Repairs”, presented a technical paper titled “DTA of Bonded Repairs on the Wing Skin of the C-130 Using Finite Elements”, chatted with “patients” at the StressCheck Clinic, and exhibited at our captivating booth inside the Sheraton Phoenix Hotel & Conference Center.
We are also planning a webinar for February 7, 2023 titled “What’s New and Improved in StressCheck Professional”. We hope you can attend this “must-see” event!

We realize right now is an uncertain time for our customers. We would like to assure you that your software and sales support needs will be met during this period of disruption.
In recent years, Digital Engineering contributor, NAFEMS instructor and FETraining.net developer Tony Abbey has put together a list of practical engineering simulation case studies, walk-thrus and software overviews for a variety of FEA software tools.
Watch as ESRD reproduces a selected set of his 3D detailed stress analysis case studies, and see how we compare with Digital Engineering’s published results!
While 2021 continued to present unique challenges and unprecedented disturbances, we hope that you found our customer support, on-demand webinars, web-based training services and overall experience with our team to be refreshingly positive.
Happy Holidays from all of us at ESRD, and we hope you’ll check out our year-end summary!
