Hello everybody ,
Im doing a stress-strain analysis on a car frame ;
This is the stress-strain graph that i made for the material of the car frame :April 1, 2022 at 3:16 pmRam GopisettiAnsys Employeethat graph is good, it is also accounding the linear terms from your MAT model (E) followed by plasticity. from 0-say 400 its a linear accentuating the linear elasticity which alos accounts for the deformation.
April 1, 2022 at 4:43 pmJakeScottSubscriberThanks a lot ive got another question please , this is very important .
So for my car bumper the elastic limit is 270 MPA , but when i plot the stress-strain curve , heres what i get :
From what i've studied , the linear line thats going from 0 to aprox 550 MPA is supposed to be the elastic region , but my yield stress is 270 MPA, so after 270 MPA its supposed to be plastic ( im sorry my english is bad)
How do i get the curve to stay linear till my yield stress than to turn to the plastic region ?
Thank you a lot for your timeApril 9, 2022 at 6:10 pmRam GopisettiAnsys Employeehow the mesh sensitivity on your model?
