predicting the forming limit diagram when sheet thickness changes
predicting the forming limit diagram when sheet thickness changes
(OP)
Hi,
I have the forming limit diagram (fld) data of a steel sheet with a thickness of 0.5 mm. However I need the fld data of 0.8 mm thick steel sheet. Is there any way to obtain this data using the fld of 0.5 steel sheet. Or is there any software to do this type of a calculation?
Thanks for your help

FLD0=(23.26+356.11*t)*(n/0.2116)
Lots of commercial software out there but it's easy enough to make your own spreadsheet and graph. See also:

Dr.Stuart Keeler is still around and occasionally still gives seminars (highly recommended):

As far as software there is everything from advanced FEA code: AutoForm, Hyperform, Pamstamp, Dynaform; to hardware and software that helps perform actuial measurement: Camsys, FMTI,Argus; to simple reporting software: APQP Parts, EQS Star.

You may also what to see
http://www.eqsgroup.com/calculations.htm
where you can plug in n-value and thickness, and the FLCo calculation is done for you.
You will also find English-metric thickness and strength converters, among others.

But first i have to learn thery of 'what FLD diagrams says exactly..'
I learned that it includes ;
-uniaxial tension,
-plane strain,
-bi axial stretching cases.
Can someone give me some document/info aobut all these tension-strain situations plss???
