Hello I would like to study the deformation of a can in relation to a plate or a ball, for this I wondered if solidworks could make me simulate this shock and thus see the deformation. For this I will model a can as a simple cylinder, then if I can I will change the material of this cylinder to put aluminum. As for the deformation and the simulation of the compression, I have no idea how to do it and I would like to learn about it.
Waiting for a response.
Thanks in advance
I'm not a SW Simu specialist but when you see the promotional videos, it seems to me that it's doable,
Several things to clarify:
- What version of SW simu do you have?
- Is it a shock or a crushing?
- You say: "Then if I can do it, I will change the material of this cylinder to put aluminum". To do the simulation, you will be forced to indicate a material, so you might as well start with the right material right away. Otherwise, it will indeed be possible to change the material.
Hello
- the answer is between yes if you want to see the first deformation and NO if you want to compress it even by a quarter (For the NO , see the explanations below)
- Yes, it is possible in part, but certainly not with an ordinary cylinder and only if you stay in the first level of elastic deformation.
WHAT YOU NEED TO KNOW
- A can is made of two parts
a) a first part stamped in several passes, which, among other things, strongly structures the resistance to deformation of the bottom.
b) a second part drawn less deeply and crimped by rolling.
If you want to make a simple cylinder it will give a weird result and moreover the constraint connectors will not be easy to install.
Moreover, as we will be in the context of very, very large displacements (an understandable term for those who have done PEF simu), it is not obvious that we can have a deformation while remaining in the elastic domain.
Why because SW simulation only stays in the elastic domain and never goes into the plastic zone. However, the compression of a can is done in the plastic field, which means that the answer to your question is more than likely NO.
Above all, you should say why you want to do this simulation.
Kind regards
Excuse me for this late answer but I wanted to study this deformation to make the analogy with a car spar, indeed the spar takes a shock but during a fairly powerful impact the spar will behave in a similar way with a can, that is to say the can will deform a little bit (as you say) and then suddenly completely To radically deform, I wanted to study how a car spar absorbs energy due to an impact. Unfortunately I wanted to simulate a shock with a can but it is very difficult to find a device that can put a force powerful enough to deform it while having the possibility to repeat this experience several times in an almost identical way, that's why I wanted to try to simulate it on solidworks but no chance! :(
The devices for shock experiments exist.
There are different methods:
- First of all, compress a spring which, when released suddenly, will give the energy to propel one of the elements (striker or striker) (e.g. https://youtu.be/P3NDyxgXmt8)
- Use gravity: the ground is fixed at height via an electromagnet. When the power supply is removed, the mass drops and hits the object to be tested.
Hello
For the last video I would say: simulation --> drop test.
For the rest I agree with what was said above: no bp to determine the behavior in the elastic domain but too complex to pass into the elastic domain.
Is it possible to have the can deformed on Catia?
For CATIA I don't know but without a doubt, for Solidworks Simulation you need to master or find someone who masters nonlinear analysis......... Good luck.......
