In this webinar we will discuss how ESRD’s S.A.F.E.R. Simulation techniques can be used to objectively verify the accuracy of engineering simulations computed by FEA.

WEBINAR HIGHLIGHTS

Why is the practice of solution verification for FEA results important? And what checks must always be performed before reporting your FEA results as “accurate”?
We will examine a variety of publicly-available and industry-applicable case studies, benchmarks and industry examples to determine the most efficient and reliable methodologies to perform solution verification.
LIVE DEMO: You will see a demonstration of ESRD’s StressCheck and its S.A.F.E.R. live dynamic results extractions for an industry example, and learn how StressCheck makes verifying the accuracy of results quick and pain-free.

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.
LIVE DEMO: You will see a 3D crack growth demonstration with Hill Engineering’s Broad Application for Modeling Failure (BAMF) software tool, which provides a robust integration between StressCheck’s DaDT/fracture solutions and AFGROW’s crack growth life prediction capabilities.

LexTech/AFGROW

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.

Hill Engineering/BAMF

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.

Testimonials

“We have been having very good success using the P-Version finite element code, StressCheck, to develop the 2-D solutions for two independent cracks in a plate. I have asked one of our AFGROW team members to model the plate and lug cases using StressCheck and compare them to the existing AFGROW closed-form solutions. [He] modeled the cases several different ways to be sure that he was getting the best possible solutions. He has verified that the bearing load option in StressCheck provides excellent results.”
