FEM simulation

The FEM truss simulator is based on the direct-stiffness-method and can be run by the following command

       [sE, dN] = FEM_truss(N, E, extF,extC)

Output is:

  • sE - stress in each edge, negative stress is from to edge expansion, positive stress is from to edge contraction
  • dN - node displacement in xyz directions

In the figure the deformed mesh is plotted with node displacement multiplied by 100 for visual illustration
