Product Description - Non Linear Fracture Toughness Testing and Analysis

PRODUCT DESCRIPTION: Non-Linear Fracture Toughness (ASTM E1820, 1921)

The Non-Linear Fracture Toughness software was written solely for the purposes of NLFT testing and analysis . The code is divided into two levels: ADbasic and MS Visual Basic. The ADbasic program includes high priority processes for waveform generation, control and data acquisition. MS Visual Basic processes include the analysis required to determine crack length and real-time calculation of the K and J parameters.

Features of the software include the following:

Compliance and DC potential drop methods of monitoring crack length
Selectable control and data acquisition rates for wide range of test conditions
Precise position control and high precision data acquisition
Real time display of load-displacement and amplified unloading slopes
Real time evaluation of unloading slopes and stable crack growth
Real time calculation of fracture toughness parameters
Complete automated control and limit functions
Storage of all force and displacement parameters for subsequent analysis
Auxiliary channel storage available
Versatile analysis software and Windows 3.0 Grapher software
Custom applications
Support of English and SI units
