SOFTWARE SYSTEMS
Fracture Technology Associates provides custom laboratory computer systems to a wide variety of commercial, governmental, and university labs. We provide all the software and hardware required to run Fatigue Crack Growth Rate (FCGR) and Non-Linear Fracture Toughness (NLFT) tests on suitably configured closed loop servo-hydraulic mechanical test systems. These are the same systems we use for automated testing in our own lab.

Software
FTA software provides an integrated approach using the latest technology in digital signal processing and MS Windows programming. The software guarantees a high degree of reliability, flexibility and ease of use for the test engineer. Two applications are currently available: FCGR (ASTM E647) and NLFT (E399, E561, E1820, E1921). Both applications include the following features:



Hardware: the ADwin Gold
The core of each system is the ADwin-Gold, offering real-time control and data acquisition. Manufactured by Jaeger in Germany, the ADwin has a dedicated Analog Devices SHARC DSP processor, local memory and high speed 16-bit analog input and output. The time-critical processes are designed to run independently of the PC operating system, so if the computer fails for any reason, the test continues and no data are lost.



FTA Reversing DC Potential Drop System
An additional option for those labs requiring DC potential drop methods of crack measurement is our own instrumentation, designed by Keith Donald to provide precision current supply and amplification.

The system is custom-manufactured at FTA and is intended to be used in conjunction with the Adwin-Gold and our potential drop testing software.
