Inventor Frame Analysis or Stress Analysis! – Some Pro’s and Con’s
Posted by Wasim in FEA, FEA-Tips, Frame Analysis on April 23, 2010
With the release of Autodesk Inventor Simulation 2011 comes frame analysis in addition to stress analysis. So the question, for some maybe, is which one to use. Well if a component or indeed an assembly comprises of a uniform cross-section along its entire length and the ratio of length/cross-section is greater than 10 then use [...]
Stress Analysis of Quarter, Half and cyclic Symmetry models!
On many occasions when analyzing complex and detailed models I have found the mesh can take for ever. This can lead to further frustration when a mesh warning appears (could be several) indicating the mesh needs to be redefined with a smaller mesh size. All this will lead to more waiting and most likely longer [...]
Autodesk Simulation 2010 Book – Review
Posted by Wasim in FEA, General, Simulation on February 9, 2010
We don’t often do book reviews in CAD User, usually because my time is usually taken up with bludgeoning my way into the latest bit of software, testing, if you will, it’s intuitiveness or its ability to withstand my heavy-handed approach. It’s usually a good test of a solution’s robustness if you can retrieve your [...]
FEA Tip of the Week
Q- Can I avoid creating high localized stress results as it affects convergence. A – Yes you can. Avoid applying loads on edges or points as this is will create high stresses (this also applies to restraints) this is because Inventor Simulation treats all components as rigid and can only perform linear analysis. Based on [...]
