    Basic FE Theory

    If you are referring to the notes in the quick reference guide I think it gives a poor explanation of the three methods I should have mentioned the notes I am referring to were obtained from the MSC site. I have attaced the notes bellow, let me know what you think. Thanks for your contribution...

    Basic FE Theory

    Thanks for your input. My question relates to the three options available in Nastran for calculating element nodal stress BILINEAR, CUBIC and SGAGE (the last two are similar). From reading Nastran notes the BILINEAR uses results at gauss points and extrapolates it to the node points where as the...

    Basic FE Theory

    Reading literature there seems to be two methods of deriving element unaveraged stresses at nodes 1) Interpolating results from gauss points 2) Directly using nodal displacements. In simple explanation how are stress derived in both cases. If you are after stress within the element i.e. centre...
