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)?
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.
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.
