High-speed Data Acquisition in Strain Measurement and Dynamic Material Testing Applications

 

Dynamic material testing  requires high-speed data acquisition (DAQ) and sensors with enough bandwidth to capture these dynamic impulses.

Oscilloscopes were used for test evaluation in the past. Analyzing the measurement and computing the material constants was time-consuming and required a lot of calculation, since this technology involved graphical analysis of measurement results.

Modern digital test and measurement technology significantly facilitates measurement acquisition and subsequent computation of material characteristics.

This webinar will give an introduction to high-speed data acquisition in strain measurement.

Topics include:

  • The right selection of your high-speed strain measurement equipment:
    • How to find the right strain gauge and adhesive for your application
    • How to  handle influences from cabling
    • How to select the right analog-to-digital converter (ADC)?
    • How to reduce the effect of noise?
  • Application example: Split Hopkinson Bar

An Introduction to Split-Hopkinson Bar Testing and Dynamic Strain Measurements

Dynamic material testing, such as in a Split-Hopkinson bar test, requires high-speed data acquisition (DAQ) and sensors with enough bandwidth to capture these dynamic impulses. This webinar will give an introduction to the Split-Hopkinson bar tests as well as discuss the required data acquisition systems for this type of testing.

This webinar was originally presented on August 5, 2014.
