Hi Jabrane,

I am not sure about the meaning of this equation, do you have any
reference? It is similar to (but it is not) potential energy in gravity
field.. would you really need it in three point bending? Don't you want
potential energy of elastic deformation instead?

O.forces.f(bodyID) # [1]


> and the displacement of each particle?


b = O.bodies[bodyID]
b.state.displ() # [2]

cheers
