Experiments were done with a linear array to perform full matrix capture from notched specimens . Total Focusing method (TFM) images were generated from these tests using CIVA software. We invite you to participate in this benchmark and present your results at a special benchmark session during the 2014 Review of Progress in Quantitative NDE meeting being held this year in Boise, Idaho.

The World Federation of NDE Centers pleased to announce a new Ultrasonic Benchmark Problem for the 2014 Review of Progress in Quantitative NDE Meeting.

We invite you to participate in this benchmark and present your results at a special benchmark session during the 2014 Review of Progress in Quantitative NDE meeting being held this year in Boise, Idaho.

PARTICIPATION IN THE 2014 BENCHMARK SESSION
We would like to invite papers that consider the ultrasonic benchmark outlined here at the next Annual Review of Progress in Quantitative Nondestructive Evaluation (RPQNDE) meeting. This meeting will be held July 20-25, 2014 at the Boise Center in Boise, Idaho. To present a paper at that session, please note that the deadline for submitting an abstract is Monday, April 28, 2014 (mark on your abstract that it is for the benchmark session) . Also, please note that the advance registration deadline for the conference is Friday, June 20, 2014. For more details of the conference, visit the website at www.qndeprograms.org .
On the following pages is a comprehensive outline of the benchmark problem being considered. You can retrieve the experimental data files at the ftp site: ftp://ftp.cea.fr/incoming/y2k01/2014_UT_benchmark/

Full Matrix Capture (FMC) acquisitions have been carried out to image notches in 4 specimens :
• specimen 1 contains vertical notches of different heights : 2, 5 and 10 mm• specimen 2 contains identical vertical notches with different ligaments : 5 and 10 mm • specimen 3 contains identical vertical notches located at inclined backwalls : 0, 5 and 10°• specimen 4 contains identical tilted notches located at inclined backwalls : 0, 5 and 10°
The same linear phased array has been used for all the acquisitions
The used system is a MultiX system (M2M) with 128 parallel channels
FMC data are recorded in Matlab files (1 file for 1 defect)
For each acquisition, the probe has been positioned so that the angle between the probe axis and the defect direction corresponds to 45°
We will give in this document:• A description of the configurations:
