Hello,
I am trying an impact of rigid body with a deformable body. I defined a ref.
point for the rigid body and applied the displacement. There are 2 steps in
my case.
step 1 : It brings the rigid body in contact with the deformable body (just
touching and no further propagation to step 2). The initial separation was
0.1 mm
step 2 : It pushes the rigid body into the deformable body by 0.2 mm.
The simulation is smooth with no errors. But, the problem arises when i see
the reaction forces in y direction with the displacement of the ref. point
through field output.
The reaction forces start acting after a delay of 0.12 mm. I would like to
know as to why this delay is happening. In some cases, with a different
model, when i defined the penetration as 2mm, the reaction forces started
after 0.26 mm or so. I checked the inputs, and they are fine.
best wishes,
mechanik
