Jan Papuga

Leader of PragTic freeware project focused on automated fatigue computation.

Leader of FADOFF project (Fatigue Analysis Documentation OFFice) - focus on:
* PragTic development
* Benchmarking various fatigue prediction methods and fatigue solvers
* Gathering large volume of data useful for it

Founder of FatLim and FinLiv open Internet databases.

Co-chairman of the 3rd International Conference on Material and Component Performance under Variable Amplitude Loading (VAL 2015).

Synopsis of FADOFF project follows:

PragTic was created as a response to the current situation in the practical industrial use of commercial fatigue solvers, which are too benevolently used by unskilled people. They are not sufficiently informed about weak points in the fatigue calculation course. A general intrinsic property of fatigue methods is that they are of empiric nature and thus any use outside of verified space is dangerous.

Producers of commercial systems do not provide any warranty on the use of the software itself or of the methods implemented in it and do not inform the user about potential deviations under specific conditions.

FADOFF consortium was thus established with several goals: 1) further development of PragTic so that it could be used for the most of common fatigue problems; 2) improvement of existing methods or development of new solutions with direct application and testing with PragTic; 3) experimental work to analyze potential experiments critical to the existing fatigue computation methods; 4) comparison of different fatigue solvers including PragTic on retrieved experimental data; 5) Internet dissemination of obtained results.

Initial phase of the FADOFF project was funded by Technology Agency of the Czech Republic in 2011-2014. Now its second phase seeking for sustainable development was started.
