Will my model break

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. :smileyhappy:

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?

 Along the x and z where?  Equal in each direction?
