Webinar: Standardize Recurring Analysis and Process Workflows Using FEA-Based Simulation Apps

Webinar: Standardize Recurring Analysis and Process Workflows Using FEA-Based Simulation Apps

Mar 18, 2021

March 18, 2021 @ 10:00 am EST

Strategies for the democratization & standardization of recurring simulation tasks via ESRD’s CAE Handbook will be demonstrated.

This webinar is now available to watch on-demand.

WATCH NOW

ESRD’s CAE Handbook

WEBINAR SUMMARY

In this 45-minute webinar, hosted by the Altair Partner Alliance (APA), we will discuss how ESRD’s CAE Handbook modernizes and streamlines the implementation of digital engineering handbooks for the standardization of corporate process workflows.

WEBINAR HIGHLIGHTS

The CAE Handbook framework allows for the corporate standardization of many engineering computational simulations. This is done by allowing companies to build an electronic or digital handbook models that captures corporate intellectual property. This enables non-FEA experts to solve many basic simulations that historically have been simplified in the form of Microsoft Excel engineering computation spreadsheets, and internally developed engineering programs that are only fully understood by the engineers who develop them. CAE Handbook guarantees consistent results and provides an objective measure of the quality of the solution.

Topics covered include:

  • CAE Handbook software overview
  • Live demo
  • Live audience Q&A

Webinar: Simulation Governance Is Critical for Reliable Condition-Based (Predictive) Maintenance

Webinar: Simulation Governance Is Critical for Reliable Condition-Based (Predictive) Maintenance

Apr 22, 2021

April 22, 2021 @ 11:00 am EST

Strategies will be explored for developing mathematical models to support condition-based maintenance (CBM) decisions via a practical case study.

WEBINAR SUMMARY

This webinar, hosted by ESRD partner Revolution in Simulation, will present a case study in which the goal was the development of a mathematical model for supporting condition-based maintenance (CBM) decisions.

The model was designed for estimating the remaining fatigue service life of high-value mechanical components, given their service history and that specific flaws (such as corrosion defects) have been discovered in them, thus enabling CBM  to move damaged component removals from unscheduled to scheduled maintenance action.

WEBINAR HIGHLIGHTS

  • Mathematical models have both intuitive, creative components and objective, science-based components. These two components must be in equilibrium.
  • What is the difference between finite element modeling and numerical simulation?
  • What is the domain of calibration and how to specify it?
  • How the outcome of validation experiments should be evaluated and reported?
  • Why is the development of mathematical models open-ended? – Why no one can claim to have the last word?
  • Why simulation governance is essential for the success of numerical simulation projects?

Webinar: Simulation Governance & Management

Sep 2, 2021

September 2, 2021 @ 1:00 pm EST

This 15-minute recorded presentation was prepared for the NAFEMS World Congress (Salzburg, October 2021). It highlights the mission-oriented nature of simulation governance and presents an example of a model development project.

This webinar is now available to watch on-demand.

Calibration of the predictor.

WEBINAR SUMMARY

The main ideas of, and the case for, simulation governance are easy to understand.  The development and implementation of a plan for simulation governance is not at all easy, however, and requires careful consideration of the mission, and associated predictive model(s), at hand.

In this pre-recorded webinar, ESRD Chairman Dr. Barna Szabó addresses some of the key issues of simulation governance, including how model development must adhere to the requirements of simulation governance in order to minimize risk and magnify reliability.

Note: this webinar was originally prepared by Drs. Szabó and Actis for the NAFEMS World Congress 2021 session on Simulation Governance.

WEBINAR HIGHLIGHTS

  • Why planning for simulation governance is mission-dependent
  • Application of the concepts and procedures of predictive computational science: Focus on model development
  • Example of a model development project: Prediction of the probability of fatigue failure of a metal part subjected to cyclic loading in the high cycle range
  • Why the open-ended nature of model development projects makes the exercise of simulation governance essential

Testimonials

  • “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.”

Testimonials

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.
