behzad majidi is still having a problem:
but, there's a little problem here.
I added to facets with a material with Young's of 100 times bigger than the
spheres;
id_Mat2=O.materials.append(FrictMat(young=1e10,poisson=0.3,density=1000,frictionAngle=1))
Rigid=O.materials[id_Mat2]
box_1 = O.bodies.append(box((0,0,0),(1,1,.001),fixed=True,material=Rigid))
box_2 =
O.bodies.append(box((0,0,4.3),(1,1,.0001),dynamic=False,fixed=False,material=Rigid))
then I set a velocity to the upper facet:
O.bodies[box_2].state.vel=(0,0,-0.001)
and I asked for the unbalanced force on the upper(or lower) ball in z
direction to be plotted:
def AutoData():
plot.addData(t=O.iter,F=O.forces.f(1)[2])
plot.plots={'t':('F')}
plot.plot()
The probable is it does not give a linear response as we expect for elastic
behavior. I was expecting to obtain a line by which I can calculate the Young
modulus of the material.
Is this because of the contact model here? or what?
