Greetings My question is regarding Can "Failure indices bond indices" be greater than "Failure indices, Maximum indices ?? [Mat8, Tsai-wu criterion used, in PCOMPG, SB also being used] e.g Failure Indices, Maximum Indices = 0.828 Failure Indices, Ply Indices (All plies) =0.015 Failure Indices...

Dear All, Greetings Need guidance regarding shell and solid interaction for sandwich panel inner core solid while outer surfaces are shell How the analysis to be proceeded? please help MPC/RBE2 and RSSCON options creating a lot of confusion and secondly, shell and solid nodes same ID can...

Thanks a lot @dmapguru. It worked.

The size is going upto 20GB and more :( for info: using PUCK criteria with 400 solution

Dear All Greetings How to manage / split output file .f06 into multiple to reduce its huge size because of large structures problems and non-linear solutions? [Most available text-editor are not able to open such big files, that's why need to customize the output to reduce file size]...

@SWComposites: not exactly, googled and downloaded one only @rybose: Thanks

Greetings, By chance, does any one knows how to obtain Puck parameters for carbon epoxy lamina especially slope P12c of fracture envelop slope P12T of fracture envelop slope P23c of fracture envelop slope P23T of fracture envelop and other parameters as can be seen in Patran while...

Dear All Greetings I have a very basic question regarding composite failure analysis I am using Tsai-Wu failure criteria, Solution seq-101, shell elements i can determine Failure index and stresses in elements My question is I want to know is the failure is because of matrix or fiber...

Thanks Jenial for your reply , let me simplify the above statement To find out the optimum number of plies with specific ply sequence pattern for sertain application (let say torque) instead of trying and apply each sequence and finding the solution for each , excel or other algorithm made...

Dear All Greetings, By chance, does any one know the good database for composite ply sequence design algorithms, excel sheets etc etc Please do share Advance Thanks AB

Hi all, i need to extract strength values from .f06 file for multiple number of plies. For that I need to select only a column Does any one knows how can i do it easily ? If such thing exist in postprocessor, please do tell Much thanks Abi

Dear All, Greetings I need your help regarding strength ratios calculation in Nastran/patran. Is it possible to use such command / entry by calling them in prepostprocessor Patran, (like bulk entry while we call for analysis , nastran solver) If yes, then how to use it? confuse with the...

Nevenick, As you know torsional stiffness is k=Torque/Thetha and first find out the thetha in .f06 file by looking against the axis where you applied moment (means if you apply moment at z axis, you will get thetha in R3)it will be in radians and once you get that and you already know torque...

Thanks Burner2k, Yes, i got the answer what i was asking for, from your reply. once again thanks cheers

Hi, I have a question regarding torsional stiffness and angle of twist in torsional analysis For the reference: I applied the moment to shaft in Z-axis I want to know which value will be giving me angle of twist ? like R3 under maximum displacement in .f06 file ??? Please explain a little...
