I've created a model in inventor that is a plate with two pins coming off of it. (Made from ABS)
what i was wondering was weather there was a way to test wether the pin would snap when a force is aplied to it? I'm also interested in how much it will flex But it isn't essential.
how can I do this in inventor??
Thanks Ed. ๐
Ed,
You would have to do a stress analysis in Inventor.
What version of Inventor do you have?
Attach your file here.
Inventor does not do fracture analysis.
It will show you where part goes beyond elastic deformation into plastic deformation.
Regretably i cant attach the actual design file but i will attach a demonstration piece when i get back to my computer.
So the plastic deformantion is a permenant change? Whereas elastic deformation is reversable? If so then i would require no plastic deformation.
Thanks Ed.
Ive attached a model. I want to apply pressure along the x and z axis to the top of the thinner rod. And then id want to know wether that rod would snap off.
Thanks Ed.
There is no material assigned.
Inventor doesn't do fracture analysis.
it should be assigned ABS plastic, and ok is there a way of finding out wether it will be irreverably dammaged?

Thanks Ed.
Along the x and z where? Equal in each direction?
What is your safety factor?
Are you intending displacement as intentional?
If so, do you have a target displacement?
Do you have a target pressure (or force)?

Of course it will , or at least at some point) bend over and not return to original condition. Do you have some target parameters?
For the X and Y one direction along either, it doesnt matter which because its round.
And I want to work out at what force it will become deformed at. Ideally it would be good for it to be subjected to 2.5N and still be "good as new".
My question is really how do i use the stress analysis and how do i interpritate the results?
It sounds like you need to hire an engineer. Stress analysis isn't something you can learn from a discussion forum, or even a program tutorial. You must have a solid mechanical engineering foundation to be able to decide if the results you get from the analysis are even worth anything.
Stress analysis is all about making acceptable assumptions to simplify the model, and choosing the correct input to examine a specific problem. If you don't understand the principles of mechanical design, you won't know which assumptions are acceptable, or which inputs are correct, or even if the results are close to reality.
ok thanks, i cant afford to do that im a student!! i guess ill just for the make it and then poke it to see if its good approch ๐
Thanks Ed.
