SolidWorks has updated it’s Simulation suite of software to include a basic tool to check for fatigue problems. The Fatigue Check plot alerts you if certain regions of your model are likely to fail due to repeated loading and unloading over infinite time. You can assess in advance the safety of your model due to fatigue, without running a fatigue study, based on results from static studies. This is available as a plot type when you run a Linear Static simulation and if you have SolidWorks Simulation Professional or higher license type. If you are curious about more in depth Fatigue calculation and crazy statistical calculations, I ran a webcast on this stuff recently which can be viewed here. The video below is a great testimony to running a proper fatigue study in SolidWorks:
A bit of a farce of course, and I love it, but fatigue analysis can come to the rescue. New in SolidWorks 2010:
- S-N material curves are now defined in the fatigue study, not in the associated studies. You can view other material properties in a fatigue study.
- You can now use stress results at a particular solution step from nonlinear and linear dynamic studies.
- When creating a fatigue study, you choose constant or variable amplitude. The Change Event Type command is removed.
- Body icons appear in the fatigue study tree to allow you to define S-N fatigue curves. Much easier
- Damage is shown as a percentage instead of as a fraction in Damage plots.
All the above is discussed in the aforementioned webcast which can be viewed here. For a copy of the presentation that goes with the webcast, you can view it as a cool Prezi below:
hi there, just wanted to tell you that your page were showing properly in internet explorer 8 but after few refreshesh it absolutely was fine again. Keep in the good work.
