High-Speed Imaging System for Dynamic Deformation and Fracturing

The high-speed imaging system consists of two high-speed cameras (Phantom V2511, 1 million frames per second, fps) and 32-channel acoustic emission (AE) sensors. AE will be monitored by 32 piezoelectric sensors (KRNBB-PC and Panametrics-V103/V153) mounted on target surface. AE data will be continuously acquired and digitized at 100 MHz and 14-bits by a newly developed AE system. The ultrasonic waveform, generated by a waveform generator, is recorded using a NI digitizer PXIe card using a sampling frequency of 10 MHz. The developed 3D digital image correlation (3D-DIC) method with two high-speed cameras will be used for the quantitative measurement of deformation fields and the identification of constitutive parameters.

MUEGGE Single Mode Industrial Microwave System

A single mode industrial microwave system (MUEGGE) consists of a power supply and control, a magnetron head, an applicator, an isolator, an impedance matching tuner, and a water load. The power supply and magnetron head generate microwave at the frequency of 2.45 GHz with a power adjustable from 1% to 100% (maximum power of 2 kW). Microwave then propagates in the WR340 waveguide in the TE10 mode and reaches a specimen in the applicator. The isolator protects the magnetron from overheating by redirecting the excess energy reflected from the specimen to a water load. The microwave power level in the environment is monitored by a microwave leakage meter to be below 5 mW/cm2 at any point.
