Hi, SConstruct checks in line 260 boost_program_options library. Do we really use it? If not, may I delete it from SConstruct? Thanks Anton ___ Mailing list: https://launchpad.net/~yade-dev Post to : yade-dev@lists.launchpad.net Unsubscribe :

Hi Vincent, I didn't see the need to find a reference for contour integral of Cauchy stress, since it is something classical in continuum mechanics courses. The demonstration is in function's documentation. I don't understand this in your paper : At this scale, a Cauchy stress in the sense of

2011-01-20 Thread Vincent Richefeu
Note that the integral is computed on deformed contour. In tblatex-1.png, tblatex-2.png is the contact point, closer to center than radius. Hence, dividing by a volume of the Voronoi sort would not be consistent with the integration domain. I don't see what other volume could be used than
