A warning message probably appears. Just click OK to continue.
Analysis is in progress until a notification appears for completion. Close all the pop-ups.
View the results. Click General Postproc >> Plot Results >> Contour Plot >> Nodal Solu.
Click Nodal Solution – Stress – X-Component of stress, Click OK.
![Page 17: Open ANSYS APDL Click Preference-Tick/Select Structural](https://reader030.vdocuments.us/reader030/viewer/2022012508/618500d275532656376a06c6/html5/thumbnails/17.jpg)
The maximum X-normal stress is obtained, SMX = 282 MPa.
The stress concentration factor Kt = SMX/the nominal stress.
In this case, the nominal stress = the applied pressure (= 100 MPa). Thus, Kt = 2.82.
The stress concentration factor Kt (D/d = 2 and r/d = 0.05) from the chart is 1.0996*(0.05)-0.321 = 2.9…
All steps for the modeling, meshing , applying for the boundary conditions and analysis are recorded in a log file.
Therefore, new parameters can be specified in the file.
To save the log file, click File >> Write DB log file.
![Page 18: Open ANSYS APDL Click Preference-Tick/Select Structural](https://reader030.vdocuments.us/reader030/viewer/2022012508/618500d275532656376a06c6/html5/thumbnails/18.jpg)
The file can be saved, for instance, on the desktop, e.g. Case1.txt. Click OK.
The file can then be opened with Notepad.
For example, if we would like to have a new model for D/d = 2 and r/d = 0.1, the corresponding parameters for fillets
can be specified.
Change values of 2.5 with 5.
Then, save as the file with a new file name, e.g. Case2.txt.
The new file can then be opened in ANSYS.
Prior to reading the new file in ANSYS, close the previous session.
Click File >> Clear & Start New.
Select “do not read file”. Click Yes if a message appears.
