2.2.9.5 Viewing Results

Previous Next

 

 

 

There are a few ways to view the results:

 

1) Report:  Depending on report type specified in Project Setup, the report can be as simple as a summary, or as regular report, or as detailed report.  In this tutorial, we selected Summary option.  To view the report, choose Report>Open result report, or click Open result report button .  The result report file opens:

 

 

The report is in a text file with file extension .txt.  The file can be saved as a different name, printed, or converted to PDF by the user.

 

2) Stress & temperature time history chart:  Choose Charts>Time History or click Time History button .  The Stress Time History chart appears.

 

 

3) Stress range histogram chart:  Choose Charts>Histogram or click Histogram button .  The Strain Range Histogram chart appears.  The chart shows cycle counts for each stress range band.  The stress range bands are grouped by the program using rainflow counting algorithm. The grouping is for reporting purpose and does not affect fatigue life analysis accuracy.  The histogram is an approximate representation of the distribution of stress ranges. The entire range of values is divided by the number of bins into a series of intervals.  The program counts how many values fall into each interval. The vertical bars represent the frequency, that is, the number of cycles in each bin. Some bins can be empty.

 

 

4) Damage ratio chart:  Choose Charts>Damage Ratio or click Damage Ratio button .  The Fatigue Damage Ratio chart appears.  The chart shows damage ratios for each stress range band and cumulative damage ratios for all stress range bands.  The grouping of the stress range bands is arbitrary by the number of bins for statistical result reporting purpose.  The actual fatigue life is assessed on each time step, not the bands.  The damage ratio line in the chart represents damage ratio by each stress range bin.  Each dot represents a bin value.  The cumulative damage ratio line in the chart represents successive additions of damage ratios created by individual stress ranges in the bins.  The last point to the very right represents the total damage ratio.

 

 

The charts can be zoomed, printed, or exported by clicking on correspondent buttons.  The styles of the chart can be edited by clicking Styles button.
