    Failure models

    Hi @Prakash Pagadala, Thank you for the efforts. So for now element deletion due to material failure is not possible with Optistruct ?

    Hi @Mrt @Prakash Pagadala, I am also facing the same issue of high element distortion. Any updates to solve this issue

    Hi @Prakash Pagadala, If I am using STRN, should I specify the Material stress limits Vi and Parameters for failure envelope. where to mention the Strain limit ? Thankyou

    Failure models

    Hi @Prakash Pagadala, I am looking for plastic material, for now I am using the MAT1 with MATS1 (table data). I am facing the non convergence error due to heavy element distortion. So I would like to remove the elements failed in the model. Thankyou

    Failure models

    Hi All, Is there any failure models available in Optistruct for implicit nonlinear analysis? I need to remove the elements once uts is reached / strain value reached ? Thank you N.K

    Fatigue sequential loading

    Hi @Prakash Pagadala, Thank you for the quick response. 1. So you mean sequential loading without TABFAT is OK ? OR 2. Creating separate events and calling all in FATSEQ card is ok ?

    Fatigue sequential loading

    Hi @Prakash Pagadala Thankyou, its working. My doubt is you have left the TID fields blank for the FATLOAD card. It doesn't require the loading time history ? How loading time history specified in Sequential loading?
  11. Thank you @Prakash Pagadala, Issue solved

    Fatigue sequential loading

    Hi @Prakash Pagadala, I have shared the files, I tried using the SQNTL in FATEVNT load collector. I got error " TID field in FATLOAD 9 must be a blank because of SQTNL in FATEVNT 10. " Tried leaving the TID field in FATLOAD 9 blank. Resulted in some other error " ERROR # 1000 *** in the input data: Incorrect data in field # 3." Please guide me how to clear the SQNTL loading errors BrakePedal.fem BrakePedal.out

    Hi @Rahul R, Thank you for the response, these files are already there at help. Please share me some more fatigue .fem files for better understanding
