Hi,

I am trying to do analysis for two different temperatures. I attached file the analysis of the beam where I need to do the breaking force . Also I attached the data file and excel of the used material. I am doing analysis of beam with with PA GF 30 at -40 and 23 C. I used the eng. stress and strain, did not convert to true, I know that need to that convergence, now we will ignore that.

At -40, the curve eng. stress and strain has brea point, it is when the construction will separate.

At 23, the curve eng. stress and strain has yield point. It is when on the construction will appear the cracks, total strain bigger than total strain at yield.

Now, I am interested how to find find force of breaking (separating, not only craks) at these two temeperatures.

The points break and yield point on the curve are not same?

Breaking point for -40C is 257 MPa and 4%; for 23 C is 195 MPa and 3,5%.

If I put that these are the same points, I will get the break force of -40 is bigger than at 23. Now I am interested how to find the break force (separating) at 23 and -40.

Can anyone chack the excel file and ansys file (18.2), are those ok.

Does anyone has the curve stress strain of PA GF 30, where has point after yield point at temperature 23 (break point). And that do comparing the break force at -40 and 23.
