Join us Wednesday, December 5th from 12:00 PM – 1:00 PM as we host a webinar with Photron high-speed camera. The webinar will be hosted by two world-class engineers who are experts in their respected fields. You’re not going to want to miss this great event!
Digital image correlation (DIC) is a widely used full-field measurement technique, in which a calibrated stereo camera pair determines the 3D coordinates of thousands of points within a dot pattern that is applied with spray paint or ink.
During rapid post-processing, reference coordinates are subtracted from each measurement frame, thus obtaining full-field 3D displacements and directional and principal strains that can be viewed as color maps, movies, vectors, time histories, etc. The system can determine local displacements at the micron level despite significant rigid body motion.
This seminar will discuss the general benefits of full-field measurements, which include visualizing strain gradients and hot spots, verification, and iteration of finite element models, and making otherwise impossible measurements. Digital high-speed cameras have been used for DIC at speeds up to 300,000 frames per second, but many applications only require 1,000-10,000 frames per second. Much more data is obtained much more easily than with strain gauges, draw wires, LVDTs, etc.
We will review important high-speed camera features and options as well as the different price/performance points available in the Photron product line, and will provide details on the new FASTCAM Nova camera model and PFV4 control software.
Numerous high-speed applications will be shown, including:
Biomechanics Impact Testing
Helmet Ballistic Impacts
Hopkinson Bar High Strain Rate Testing
Explosive Loading of Sheet Metal
Rotor Blade Vibrations on Hovering Helicopter
Rocket Nozzle Deformations
Parachute Strains During Drop Tests
Microelectronics and Device Drop Testing
Air Blast Effect Testing
