Introduction
Application Workshop Program with 12 Experts in May
You are invited to participate free! Get your questions answered! We would appreciate it if you would fill out the Registration Form anyway and subscribe to the mailing list.
This month 9 papers of the International Symposium NDT-CE '95 focus on Ultrasonic Testing in Civil Engineering. The Table of Contents of Proceedings shows 195 papers on 1346 pages in vol. 2. The next NDT-CE '97 is will be APRIL 8-11 in Liverpool UK. For readers who can't attend, Dr. Martin Krause, a specialist in UT of CE will participate in the Ask the Expert Forum of our May Workshop.

Ultrasonic thickness gauge for multilayer plastic fuel tanks
An interference method using ultrasonic tone-bursts employs a frequency progression wherein a frequency producing a minimum in the reflection echo from the barrier layer identifies the thickness of the barrier layer. A new US Patent from Ford Motor C.

Research Developments in the Specification of Adhesives
A study to determine accurately the potential of adhesives was funded by the Body Research Department at Ford and ACME. This measures acoustic wave propagation parameters from which mechanical moduli are derived as functions of frequency.

Resonant Inspection
Magnaflux now offers a patented new NDT technology that was initially developed by Los Alamos National Laboratory. Technically, it's resonant ultrasound spectroscopy, but its simply called Resonant Inspection (RI).
(More through Magnaflux on IndustryNet)
Ultrasonic Resonance Spectroscopy for Conrete Structures
New inspection equipment has been built and tested which has been fitted inside a rugged, portable personal computer to be used in conditions ranging from laboratory to construction site. The project aims to evaluate the new techniques on pre-cast concrete units and concrete bridge structures etc.. The project is led by Instrumentation Innovation Ltd and sponsored by the EC's Brite-EuRam programme and PSTI.
