07.212022Validation of CIVA modelsCategory "CIVA Software" | No comment

While CIVA validation tests are constantly being performed, a specific effort has been done by the CEA and EXTENDE teams in the period 2010-2017 in comparing a lot of simulation results obtained by CIVA UT (and also ET and RT) with experimental trials. These results (published on our website and also in different conference papers) give credit to the accuracy of CIVA models in many situations.

The goal of this work was also to highlight the discrepancies observed when reaching the limitations of semi-analytical models, so that users can be aware about validity domains of CIVA.

Release after release, CIVA includes new features but also new models.

In particular, new FEM models have been integrated recently in CIVA UT, which lead us to update some of our validation works in order to evaluate the improvement brought by these new models. Take a look at our website to update your knowledge about CIVA accuracy and limitations!

You may focus on the following pages, in which updated result have been highlighted in bold:

UT - Corner echoes with SV mode: Generalities
UT - Corner echoes with SV mode: Influence of the notch height
UT - Corner echoes with sv mode: Simultaneous influence of the notch length and the refraction angle
UT - Corner echoes with sv mode: Conclusion and phenomena explication

04.062022The EXTENDE Inc. team is growingCategory "More to Extende" | No comment

EXTENDE Inc. opened in 2011 with just one employee, Vice President Erica Schumacher. During the past decade, EXTENDE Inc. has relocated to Virginia, and our product offerings have greatly expanded, but our staff has not.

Now that is changing too!

We are pleased to announce that Starr D'Auria has just joined EXTENDE Inc. as an NDE Engineer. She has Bachelor of Science in Mechanical Engineering from LeTourneau University, Level II training in VT and UT, additional training in ET, RT, PT and MT plus vendor oversight experience with both NDT and welding. We are very pleased to have her join our team, bringing her enthusiasm, knowledge and interest in continuous learning to EXTENDE Inc..
