The Laboratory for Nondestructive and SHM studies

The Laboratory for Nondestructive Evaluation and Structural Health Monitoring studies was established in September 2006. The facility consists of about 750 square feet of dust-free space, which contains:

  • Ultrasonic Testing: Tektronix AFG3022 arbitrary function generator (2 output channels); OlympusNDT-Panametrics high power (max 400 Volts) signal generatorcommercial broadband; Immersion Transducers; OlympusNDT-Panametrics Ultrasonic Transducers;.
  • Acoustic emission (AE):8-channels Physical Acoustics Corporation PCI/DSP system with waveform module including a notebook computer and AE-Win software; AE Pico, WD, and S14 AE-transducers.
  • Modal Testing: 8-channel, line-powered, ICP® sensor signal conditioner; 1/4 in. pre-polarized condenser microphones, free-field, 4 mV/Pa, 4 to 80k Hz (± 2 dB); Modally Tuned® Impulse Hammer w/force sensor and tips, 0 to 100 lbf, 50 mV/lbf (11.2 mV/N); 086D80 Miniature Instrumented Impulse Hammer w/force tips, 0 to 50 lbf; accelerometers.
  • Thermography: One FLIR InfraCAM with ThermaCAM Quick Report software. One FLIR thermal imaging camera.

 

The Lab also features equipment and instrumentation like:

  • Nd-YAG Pulsed Laser 532/1064nm;
  • One optical table;
  • Lenses, mirrors, and optical stands and posts;
  • National Instrument-PXI 1042Q chassis with arbitrary function generator and multifunction Data Acquisition System;
  • National Instrument PXIe-1062Q, with 8-ch digitizer and 100 MHZ AFG.
  • Unidirectional and omnidirectional acoustic microphones;
  • Two oscilloscope one of which is a Lecroy Waverunner 44Xi 4-channels oscilloscope (with PC incorporated running under Windows XP)
  • Six personal computers and two laptops running under Windows XP or Windows 7 operative system.
