Webinar: Democratization of Simulation Governance-Compliant Sim Apps

Jul 29, 2019

July 29, 2019 @ 1:00 pm EST

Strategies will be explored for democratizing engineering simulations via Sim Apps which are: 1) based on the latest Numerical Simulation technologies, 2) available in Commercial Off the Shelf (COTS) form, and most importantly 3) Simulation Governance-compliant.

This webinar is now available to watch on-demand.

RevSimJulyWebinar — This joint ESRD/Rev-Sim webinar will explore Sim-Gov compliant Sim Apps for democratization of simulation.

WEBINAR SUMMARY

When utilized by engineers without specialized training, simulation technologies (and Sim Apps) based on legacy FEA technologies struggle to deliver trustworthy solutions due to their inability to objectively measure & report solution quality, an essential requirement of Simulation Governance (Sim Gov). This uncertainty inhibits true democratization of engineering simulations. So what is needed?

In this timely webinar, we will discuss why it is essential that Sim Apps implement Numerical Simulation technologies which enable the practice of Sim Gov in order for the vision of democratization of simulations to be realized, as well as why it is important for engineering managers to get on the Sim Gov train sooner rather than later.

WEBINAR HIGHLIGHTS

This four-part webinar will be jointly presented by ESRD and Revolution in Simulation (Rev-Sim), and will explore the following questions and concepts:
- Part 1: What is a Simulation Application – Sim App?
- Part 2: Why is Simulation Governance compliance critical for the development and deployment of FEA-based Sim Apps?
- Part 3: What FEA technology is required to support the democratization of Simulation Governance-compliant, Commercial-Off-The-Shelf (COTS) Sim Apps?
- Part 4: Demonstration of a Simulation Governance-compliant, FEA-based COTS tool supporting the A&D Industry for the democratization of engineering simulations (ESRD’s CAE-HB)
LIVE DEMO: You will see a live demonstration of ESRD’s CAE Handbook, a COTS, Sim Gov-compliant Sim App based on ESRD’s StressCheck Professional numerical simulation technology.

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.

“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.”
