Dassault Systèmes welcomes Safe Technology!

By Mark

I’m very pleased to announce that Dassault Systèmes has acquired Safe Technology, Ltd., the developer of the fe-safe durability simulation application suite.

Even if you haven’t used their products, you’ve probably heard the name – Safe Technology has been a partner of ours for over 15 years, providing a fatigue solution to Abaqus users through fe-safe. As an add-on to Abaqus/CAE, fe-safe uses proven techniques to accurately determine the fatigue life of metal components under complex cyclic loading. fe-safe combines finite element analysis results for multiple loading conditions from Abaqus with the cyclic load history to predict the life of the component. Reading from & writing to the Abaqus results files allows the users to view fatigue results in Abaqus/CAE or Abaqus/Viewer as contour plots for damage, fatigue life and safety factors. Similar interfaces are available for many other leading FEA product suites.

In addition to fe-safe, there are several complementary modules available which expand the capabilities of fe-safe to account for specific applications, such as composite materials, creep and  thermomechanics.

Check out this short video tutorial for an overview on fe-safe, and it’s use in solving Fast Gear Fatigue Analysis example.

This technology can (and to a degree, already has) benefit the analyst in the quest for a complete, unified solution to engineering problems. We’re all really excited to welcome our new colleagues and begin our journey to provide an even better 3DEXPERIENCE with this exceptional acquisition in the field of durability & fatigue  :-)

Professor Plum with the Wrench? Abaqus FEA Knows

By Tim

No, it’s not the famous game “Clue”. It’s the use of realistic simulation to perform forensic studies of skull fracture.

While, for the average person it is a bit gruesome to think about, medical examiners and police investigators are often faced with the need to determine how and why skull fractures occur.

Was the head injury caused by an accident or was the injury caused with the intent to murder the victim?

Researchers at the Institute of Forensic Medicine at the University of Copenhagen, in cooperation with the Technical University of Denmark (DTU), are using using technology from Simpleware (a SIMULIA partner) to transfer CT-scan data into SIMULIA’s Abaqus FEA software.  This allows them to gain a deeper understanding of the mechanics and forces that cause severe skull injuries.

While the researchers consider their current studies as preliminary, these represent a critical step on the path to developing a general tool for supporting medical examiners with easy, achievable and accurate numerical simulation to support their judgment regarding the cause of death.

To get more details, check out the complete case study in the latest issue of INSIGHTS magazine  here.

Are you as surprised as I am that Abaqus FEA software (traditionally used to study the performance of mechanical systems in cars and airplanes) is being used in forensic head injury research?

Verney Yachts Ocean F1: Part 2 (Biz + FSI)

By Tom

Hello Everyone!

One of the things that interest me most about Verney Yachts is the amount of business acumen and collaboration skills that you must have to be able to drive a project forward. It’s impossible to get a project like this down the slipway without collaborating with other people and organisations.

To that end, Verney Yachts are working with Capvidia, a partner of Dassault Systèmes and now Verney Yachts. Tim has used FlowVision CFD coupled with Abaqus to perform a Fluid-Structure Interaction (FSI) simulation.

The FSI analysis simulates the above surface aerodynamics of the boat, and is critical to V39-Albatross’ success.  It establishes overall aerodynamic forces and moments acting on the boat with different control inputs. Multiple analyses are conducted all with different boat velocities. This process helps the Verney team tune the control system to minimise control cross coupling and to maximise forward thrust, whilst maintaining roll balance of the overall boat.

Also part of Dassault Systèmes’ Passion for Innovation programme, the Verney Yachts team is using SolidWorks for the structural 3D design and Abaqus for realistic virtual testing. These tools are critical to the on time, low cost design and build of the boat.

As Tim Clarke, lead engineer and founder of Verney Yachts mentions:

“One of the side effects of building a keel for such high speed sailing is that it becomes very sensitive to twisting under load. We’re using Abaqus to tune the carbon fibre composite keel to minimise twisting across the speed range.”

It’s this perfect example of working collaboratively with multiple partners that drives projects like V39-Albatross on to break world records!  Do you agree?

Tune in next week for more on Verney Yachts. I’ll be looking at the project goals and what breaking a world record for speed sailing actually involves!

Cheers,
Tom
