If you use a Mac, it is unlikely that these will render properly (so go sit at a PC in your university computer lab to look at them). Make sure to use slideshow mode, as these have many animations!
MohrCircleFiles (zip file contains two PPT lectures and one Mathematica file)
This program allows one to convert between the various elastic constants. If “Evaluate” is chosen in the downloadable version, the numbers entered below the chosen elastic properties are calculated, otherwise the Mathematica file displays the results symbolically. Continue reading
