The VJ Tech Bender Element Testing;

Non-destructive way of determining the small strain shear (GMax)
Top Cap and Base Pedestal have piezoelectric elements which protrude into the sample
A wave is sent through the sample from the Transmitter in the Top Cap to the Receiver in the Base Pedestal and the received waveforms are compared using our software
For S-Waves, the shorter cable (Parallel A) connects the Top Cap Lemo connector to the Top (Tx) socket on the Bender Scope and the longer cable (Serial B) connects the Base Pedestal Lemo Connector to the Base (Rx) socket on the Bender Scope
These two cables are then interchanged for sending P-Waves
Horizontal bender elements can be inserted on opposing sides of the sample and sealed with specially adapted grommets
Signals are processed by our Bender Scope and sent on to PC
