problems with abaqus
(OP)
Attached is a video of my model as it is impacted by a rigid part. This is a bone impacted by an analytical rigid part.
There are three problems:
the analytical rigid part in the part module appears as a rectangle (which is how it is desired) however in the simulation (visualization module) it appears as a thin line (please watch the video). I would like to keep the original shape of this part...but how? and why does it change in the first place?
The second problem:
the rigid part is not making any contact with the bone, it just seems as if it is exerting a force toward the bone that causes the bone to deform but that is it. There is no actual contact! I applied a surface to surface contact, with a kinematic contact method, assuming it is frictionless.
Third problem:
the bone is bending too much! this is erraneous. I need to define a point at which elasticity of the bone no longer holds (I have defined elastic properties to the bone). How can i do this?
I will be immensely grateful for any help!
attached is the simulation video please check it out!!





RE: problems with abaqus
Contact doesn't seem to be made as I'd expect high stresses at the contact points at the top and bottom of the rigid part. Check to make sure you've applied the right forces.
Can't help with the breaking point of the bone, sorry.
