CONTROLLER

​​

v.20260609: OP calculation cutoff for small slope counts

• BIN (ADX, ADG): added check in crack length calculator to completely bypass OP averaging / calculation when the number of slopes per crack length calculation is less than 8 instead of yielding NaN

• GUI: added notification in the log file to tell user when the OP calculations are not active

​

v.20260605: Kmax stop criterion, lineEdit formatting

• GUI: changed the way whitespace is handled in the GUI; no longer forces a "0" value upon deletion of field but catches the whitespace upon sending to the controller.

• GUI: set the number of significant digits in the dashboard and rolling avg table for APD, RPD to 5

• GUI: added maximum load value in the log file at the end of the test

• GUI: added executable version number to the start of the log file

• GUI: set current switching ON as default for all PD crack measurement options

• GUI: corrected lineEdit formatting for Sy, UTS, Emod, and PDGL to account for blank input

• GUI: fixed read error in min/max da/dN stop criteria that would pre-emptively call an error stop dashboard as user entered rates in scientific notation

• BIN: (ADG, ADX): added Kmax as stop criterion

​

v.20260515: Append log file with stop criteria

• BIN (ADX, ADG): controller now sends specific information about test stop mode to GUI

• BIN (ADX, ADG): fixed Soft Stop to work with multiple stop criteria

• GUI: log file now tells user what stop criteria ended the test and their comparative values

• GUI: fixed log write error if user selected displacement as a stop criterion

​

v.20260508: K control load direction lock

• BIN (ADX, ADG): forces load to only increase for K-inc. tests and decrease for K-dec. tests. (this had only applied to K-dec. before this version

 

v.20260504: HUD divide by zero error

• GUI: HUD "norm" text fields had divide by zero error before initial crack length measurement; fixed with small delta in denominator

​

v.20260501: Set cycle interval start point

• BIN (ADX, ADG): allows user to set cycle count to start using cycle intervals

• BIN (ADX, ADG): slope counts now change based on cycle interval results

• BIN (ADX, ADG): pause peak indexing now carries through to subsequent segments in a test session

​

v.20260429: ADG updates

• BIN (ADG): n_begin_counting fixes compatible with ADX

• BIN (ADG): exempted dwell cycles from SoftStop altogether, eliminating the extra cycle at the end after the STOP command

• BIN (ADG): cycles to begin PD / compliance calculations set to 10 from 40

• BIN (ADG): peak indexing approach truncated for frequencies under 0.5 Hz

​

v.20260427: minor XML output fix

• GUI: fixed LUT output command for flat bottom hole specimen (incorrect index)

​

v.20260424: Corner crack solution

• GUI: introduced constants representing spec types in MainWin to better facilitate adding / removing specimen options

• GUI: added corner crack specimen option using Roe Coffin PD solution (validated with legacy SW)

• GUI: corrected Rigid SEN K solution (missing sqrt operator)

• GUI: corrected compliance / PD labels in HUD to switch based on measurement method

• GUI: added "norm" output for normalized PD

​

​POSTPROCESSOR

​

v.20260707: Multiple inputs

• fixed inX translator to properly transfer "compdcpdstress" parameter for compliance tests (enables ACR threshold calculation option in FTA software)

• also changed inX translator to properly order the dataframes to match the controller output

• added "append" feature to analyze multiple inputs; MUST BE THE SAME SPECIMEN

 

v.20260625: User manual and ordered dict fix

• Added "Manual" option to open the latest version of the postprocessor manual

• Fixed ordered dicts to ensure only string types are used when writing to them; adjusted associated commands accordingly

 

v.20260427: Corner crack solution

• added corner crack solution to solver

 

v.20250912: ASTM E399 calculator

• Added ASTM E3076 curve fitting routine (universal X-Y slope calculation)

• Added ASTM E399 K1C calculator for C(T) and SEN(B) specimen types

• K1C calculator allows for XML input along with standard 2-column and FLCGS style .csv input.

​​

v.20250811: Metric analysis fixes

• all units are meters or MPa sqrt(m)

• visual correction input uses METERS (for now)

• corrected .inX converter to send meter unit dimensions

• corrected unit_mult values in populateGUI

• added metric unit labeling for SF specimen

• corrected XML dictionary dimension values to mm; only CC variables are in meters.

• improved labeling of units on plots​​
