very grateful for your sharing! thanks! Do you want to make some videos about the fatigue progressive damage? It will be useful for me.

hello,Im a new learner for umat,I still dont under stand the number of material-depvar-number of solution-dependent state variables related to which parameter in the scription? and the variable number of controlling element deletion is related to the statev()? Im trying to use Ur hashin umat scription :)

[@hnrwagner]

could you rephrase your question? I do not understand it, maybe use a translator.

[@1017halo-rw4yw]

or U have a vedio for that umat hashin scription but I miss it?(I didnt find it)

[@hnrwagner]

@@1017halo-rw4yw dont have a video for hashin umat, only for vumat

[@1017halo-rw4yw]

sorry for my poor English. I just wanna know 2:35 in this vedio, the depvar parameter depends on what?I mean there are two parameters in depvar.

[@hnrwagner]

@@1017halo-rw4yw depvar depends on damage parameter 1 to 6 and failure indicator 7-12, and and indicator for element deletion - 13 dont know what is your problem, if you do not understand such easy code you should starte with the first video in the series.

I supervise PhD students who work on buckling behavior can you help them?

[@hnrwagner]

depends on the exact problem, but probably yes

@@hnrwagner that's great, thank you very much, i will contact you later by email for more details about the problem.
