My own DEM(Discrete Element Method) program's solution for static problem seems strange.
I use my program to calculate the displacement of a cantilever under static pressure:
1. it seems my program shows convergence for static problem as the mesh gets denser. As the mesh grows denser(that means the particle becomes smaller), the displacement(of y direction) of the free tip becomes smaller.
Professor Ed Berger, Univeristy of Virginia Mechanical Engineering, is featured in the Chronicle of Higher Education for his use of web technologies and, in particular, "video solutions" for teaching undergraduate mechanics courses.
Since I am an alum of the University of Minnesota, when I was a PhD student I lived only a few blocks from the site of yesterday's catastrophic bridge collapse in Minneapolis. The statics analysis of a truss is almost the first thing learned by every undergraduate engineering student, and appears to be relevant here. It is interesting to see words like "fatigue crack" and "vibrations" in the news . In light o
