I would like this elastic band in Soft Body mode to be deformed in this way by another object. My simulation is fake and extremly basic it's just to show the event.

    is your elastic supposed to stay rigid and horizontal on each side? – moonboots Jun 21 '21 at 14:37
  • @moonboots ow thank you. Not necessarily, I plan to apply this procedure to a lip that is deformed by teeth when we stretch it behind – FlowHoa Jun 21 '21 at 14:41
  • so you don't expect the object to create 90° angles like that? rather a curve? – moonboots Jun 21 '21 at 15:32

    If my rubber band did that in real life, I would freak out or think it was magnetized or something. – TheLabCat Jun 21 '21 at 18:45
  • @moonboots exactly. My goal is that soft body mesh stretch like an elastic when collising with that cube. This would mean, logically, that the mesh must have a thickness so that a stretch can be done without ending up with faces which cross between them? – FlowHoa Jun 21 '21 at 22:38

    @ZargulTheWizard yeah lol like a cartoon when a metal bar keep the shape of some one's head – FlowHoa Jun 21 '21 at 22:48
  • @moonboots another fake sim (nearest expected) link – FlowHoa Jun 21 '21 at 22:58

You should try with Cloth instead of Soft Body, the cube needs to be set to Collision, then tweak the factors to make your cylinder rigid enough, especially the Stiffness values (here 100/100/100/300):

  • Nice ! It bothers me that you modeled all this when I could have given you my blend file! You helped so much. So easy. I think I didn't catch very well the Soft Body's context of use. – FlowHoa Jun 22 '21 at 21:48
  • it may be possible with soft body as well – moonboots Jun 22 '21 at 21:51
  • I would abuse to ask you something else... in case that this rubberband has an armature (a chain of bones all long), is the combination healthy with cloth property ?... – FlowHoa Jun 22 '21 at 21:55
  • maybe you should describe the whole thing you need to do. Also, if you have different sequences, you may need to use a technic or another depending on what you need – moonboots Jun 22 '21 at 21:57
  • This will be the subject of another topic otherwise I will confuse this one. I do the rigging of a mouth. Therefore I wanted the lips to have an elastic property which undergoes the collision with the teeth. – FlowHoa Jun 22 '21 at 22:04
  • maybe you should simulate with bones rather than using physics? seems to me more adequate but you may have good reasons to use physics? – moonboots Jun 22 '21 at 22:07

    maybe you should also look into Spline IK or Stretch To constraints? https://blender.stackexchange.com/questions/116124/how-to-rig-a-cartoon-style-hose-limb-cartoon-arm/116128 – moonboots Jun 22 '21 at 22:21
  • lips are yet deformed by armatures combination (bones that deforms mesh and others that only role as muscle) this and see the slice view link I want the lips to collide with teeth with realism that only physics give. – FlowHoa Jun 22 '21 at 22:31
  • maybe ask a new question with a precise description of what you want to achieve, what you presented here was a solution that may not be the most adequate – moonboots Jun 22 '21 at 22:39
  • I could not describe my request more clearly. In any case you have put me on good tracks, thank you so much – FlowHoa Jun 22 '21 at 22:42
