can anyone suggest, what kind of study analysis to use for this problem in solidworks simulation. Cyclic loading problem.
Yes. The sequence is to establish the stress field, then, couple the stress field into a new fatigue study. There should be a built-in tutorial showing an example. Hope that helps.
Please do not post questions from the actual exam here or anywhere else!
He is asking a question from the sample exam, it's OK.
I am just learning this side of Solidworks myself or I would answer his question.

Can you please post a link which helps me to go to the sample test for CSWA Simulation in SolidWorks.
The "Fatigue" study should get you an answer, but you'd have to get the stress field at that location, first.
Thank you. Can you please give a little more detailed description of the sequence of steps involved to get the final answer?
I still get 10% as the answer. The actual answer in the test results section was 95%. Not sure where I was wrong. The only doubt I have is in the load section I used Zero Based (LR=0) condition. Not sure if thats causing an issue.
Well, you probe the result in the middle of the section of the part, where the stress is low. The point in the example is on top edge of the part, where tensile stress is high. If I run this I can probe between 95% in the 2 corners and up to 99% in the middle of the top edge of the beam.
I still dont get it even if I do it at the top surface. BTW I used the probe tool to determine the value.....how did you do it to determine the value at the top tip?
Create an offset plane from the appropriate one of the three global planes in your part with a distance of 2cm. Then use that plane to create split lines on your beam, go to Curves > Split Line and use the "Intersection" option, first select your plane then use a Selection Filter (F5) and toggle on "Filter Bodies" and select your beam for the second selection field in the Split Line command. You could also only select the top face of your beam to split, but I like to pick the whole body.
Then back in Simulation, re-run your mesh and solve, then use the Probe tool and instead of "At Location" use the option "On selected entities" select the top edge of the group of split edges and click "Update".
If the numbers are not very readable (i.e. 10+e7 or such) go out of the Probe for a moment, double-click on your stress plot and change your units from the default N/m2 to N/mm2 which are generally much more readable for most structural engineering stresses.
Kevin. Thank you
Good explanation and exactly how I did it!
