We are trying to analyze the failure of a forging die of a flange. The stationary die got cracked during the operation. So we are trying to find out a solution for the same. We are planning to use Altair HyperWorks to simulate this event. Details of corresponding die:- Die Material - DIN 2714 Hammer - 16 tonnes(42000 kgf) Flange material - Titanium- 6Al-4V Flange temperature - 870-950°c Can you Please suggest the commonly used method used for Modelling and Analysis. Thank You.
Hi; I'm working on Hypermesh V13.0 and I have to mesh a cylindrical die oncoming from Solidworks ( Save as .STEP AP203). On Hypermesh I want to decrease the external diameter of the die for exemple I want to mesh the die with this different diameter : Ø40 / Ø35 / Ø30 / Ø25. This operation is possible with Solidworks but it's very long lasting because I have to mesh 14 die with four different Ø (--> 56 similary meshing). And for my simulation is better if I have the same meshing on every diameter. My approach for this is : 1st : I import geometry which is step file type : For beginning I import a die Ø40. 2nd : In "GEOM" tool menu I use quick edit for decrease my Ø; for this I use the washer split with an offset value : 2.5 (to have 5mm on the Ø). After I supress the older lines with toggle edge (the older lines are on dotted line). --> And now I fail to mesh my new geometry (with F12 tool menu) When I use (size and bias) : Surf --> Display --> Mesh : The older lines (dotted) are meshing. --> Surf --> By Window --> I select the lines which I want meshing --> The older lines aren't meshing () but I don't have mesh on the new external surface of the die as the die is hollow. --> OK // --> External surface NOK I think my approach for decrease the external diameter isn't good. I think I have to create a new surface but I just create news lines. For your information I don't have the center of my die in hypermesh I hope you understand my problem and you can help me.
