Note! This calculator uses "Digital Curves" as material property inputs.

This page has been replaced by providing calculators in the
materials database section. The reason for its replacement is that one
needs to create a giant pile of *_fitted.html files somewhere near the
executable code, an arrangement which becomes unweildy when there are
many files to be fitted and maintained. If a user has just a small database of
materials of interest, it may still be manageable; thus I have left the
page available. The fitted curve files however may not be updated to the
most recent versions, and a potential user should check the entries in the
materials data base
section for the most recent updates.

1. Pick Your Material (click on Radio buttons):

2. Enter Elastic Kt*Nominal (or Finite Element) Stress History (Rainflow counted cycle sets) Below:

MPa !

3.


If you wish to run this program on your own machine (get Linux?) and download & compile this file:

saefcalc1.f.txt (66K) Version 1.6 (last fix, May 2005)

GNU Licensed Open Source Free Software . A complete copy of the GNU license is available from http://www.gnu.org/copyleft/gpl.html


After download it can be compiled and run with the statements:   

      mv saefcalc1.f.txt saefcalc1.f
      f77 -g saefcalc1.f -o saefcalc1
      ./saefcalc1 sae1015_fitted.html 150 -150 1  > temp
(you will need to create or download some of the "fitted" data files above)

Results can be viewed and plotted with the following statements:
View all output:
       more temp

View results:
       grep xcalc2 temp
       grep xcalc3 temp

View stress-strain loops for plotting:
       grep plotloops temp

View damage per input block:
       grep plotdam temp

Other versions for input of a single rainflow file is also available:
saefcalc2
saefcalc2e (strain input version)
