There is a "math" option to construct the forming limit curve as described in https://2022.help.altair.com/2022.1/hwdesktop/hwx/topics/panels/fld_panel_defining_flc_t.htm . What is hiding behind it?
We have the standard formula commonly used in Industry to get the point highlighted below.
Here n : Strain hardening of the material, T thickness in mm. The left side is a 45 degree line in the True strain space.The right side is created using the equation.
are you referring to this?
That is the link I referenced and the description of the mentioned Math option, yes. Are you implying that all that is happening behind the scenes is applying the circled formula? If so, I am confused about how that results in an FLC.
No, it is a part of the overall calculation.
Can you please be a bit more specific with your request? What is your doubt
The "Math" option is a black box. A user inputs the n and t, and something happens to output an FLC. I am interested in what that something is in detail.
