2.2.2.1 Creating a New Project

Previous Next

 

 

 

To create a new project,

1) Choose File>New..., or click New button  on tool bar.  The New dialog box is displayed.  Check Manually input radio button.

 

 

Note:  The Use stress type group box is for ANSYS result file option; checking any radio button in this group has no effect on manually input project.

 

2) Click OK button.  The Manual Input dialog box is displayed.  From the Stress Unit drop-down menu, choose MPa; from the Stress Method drop-down menu, choose 6 component stresses + 6 component total strains.

 

 

3) Under 6 component stresses tab, click Import file button.  In the pop-up dialog box, Component_stress.txt data file, and click Open.

 

 

4) Under 6 component strains tab, click Import file button.  In the pop-up dialog box, select the Component_strain.txt data file, and click Open.

 

 

5) The data files for stresses and strains are imported to the data editor.  The counter meter shows 304 stress counts and 304 strain counts. The green color in the counter indicates that the number of strains matches the number of stresses.

 

 

6) Click Temperature tab.  Enter temperature value.  If not entered, the program will default the value to 22 degree Celsius. The radio buttons Constant Temperature and Temperature History are for time history type of loading analysis, whereas when Constant Temperature is chosen, the user only needs to enter a single temperature value across the entire time series; when Temperature History is chosen, temperature values are entered for each and every time step.

 

 

Click OK button to confirm and close the window.

 

Note: For Basquin-Coffin-Manson fatigue model, the stresses are for mean stress effect purpose only.  If None was selectted in Mean stress criterion drop-down menu (see Section 2.2.2.2 Project Setup), stresses have no effect on the results.  In this case, the stresses can be any number (e.g. all zeros), but the number of stresses must match the number of strains in the data entry.

 

 

7) Now the project is created and the home window displays.  Set Time Unit as step.

 

 

To make changes on the manually inputted data, choose Edit>Edit Manual Input or click Edit Manual Input button .  This will bring back the Manual Input dialog box.

 

8) Save your work by clicking File>Save... or Save button . The Save FatiguePlus file dialog box displays.  Select the desired folder in which to save the file.  Enter the file name of your choice in File name: box.  The Fatigue+ files are identified by .fp extension.  If the .fp extension is omitted, the program will add the extension automatically. Click Save button.
