Webinar: Intro to Fracture Mechanics for DaDT Solution Automation

Oct 8, 2020

October 8, 2020 @ 1:00 pm EST

Strategies for the automation of durability and damage tolerance (DaDT) solutions, driven by Sim Apps designed for the computation of FEA-based total beta factors, will be explored.

This webinar is now available to watch on-demand.

WATCH NOW

WEBINAR SUMMARY

In this pre-recorded 2 hour webinar we will discuss the creation of Sim Apps for the automatic generation of complex, solution-verified 2D and 3D beta factors via the integration of StressCheck's parametric FEA engine, the Windows Component Object Model (COM) and Microsoft Excel VBA.

WEBINAR HIGHLIGHTS

In Part 1 of this webinar series, the following topics are presented:

  • 3D StressCheck Fracture Mechanics demo
  • Overview of linear elastic fracture mechanics (LEFM) parameters for fatigue crack growth: SIF’s, J-integrals and beta factors.
  • Computation of LEFM parameters in StressCheck.
  • Beta factor compounding pros and cons.
  • FEA-based total beta factors.
  • Why use StressCheck for LEFM?

In Part 2 of this webinar series, the following topics are presented:

  • What is a Sim App? And how can they help DaDT analysts?
  • StressCheck’s COM API
  • Sim App Case Studies for DaDT
  • Live Sim App Demo

ASIP 2022 Conference Recap

ASIP 2022 Conference Recap

Dec 8, 2022

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!

Testimonials

  • “Accurate and reliable stresses and Stress Intensity Factors are required for determination of static and residual strength and for crack growth analyses in analysis tools such as AFGROW. For some geometries, industry solutions are either insufficient or nonexistent. The geometry, applied forces, and crack shapes and dimensions must be modeled reasonably well to obtain useful engineering data. The p-version finite element software StressCheck (ESRD, Inc., St. Louis, Missouri, USA) is used to demonstrate how accurate finite element solutions can lead to good quality engineering analysis.”

Testimonials

“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.”
