High velocity impact of rigid impactor on composite using VUMAT subroutine

[@wenz5509]

Hi, your tutorial is really helpful, I am looking forward to your videos on how to write a subroutine in detail.

[@Potentflowconsult]

Nice, thank you. Don't forget to post the video on VUMAT routine as you promised...Thanks again

[@mohdsuhairilmeon6117]

hi, can you provide me with the link to get the paper? In your example, thank you

I am facing a problem while partitioning the cell on extruding/sweep edges from 13.00 to 14.00 covered in this video

[@vaibhav8009]

why this "warning LNK4210: .CRT section exists; there may be unhandled static initializers or terminators End Linking Single Precision Abaqus/Explicit User Subroutines" is coming while running with vumat subroutine

[@muneerahmed9263]

Thank you so much for the video. how to use cohesive in vumat subroutine. I tried but it is showing an error

[@jiaxuanli792]

hashin criteria can't be used in the case of high velocity impact, don't care rate depedent failure?

[@OROMIAKIYAOkTube]

Why i am getting this message brother .\hashin3d.for:15: Error: Can't open included file 'vaba_param.inc' Error: Last command making (build\hashin3d.o) returned a bad status Error: Make execution terminated * Failed *

Hello sir, I am getting error as excessive element rotation what to do?

[@alirezabayat6074]

یه سوال دیگه هم داشتم ... آیا شما تا حالا تجربه شبیه سازی ماشین کاری کامپوزیت رو در آباکوس داشتید؟

[@ghumakkad_ladka8022]

Can you please make a video tutorial for simulating eroding projectile and eroding target in abaqus software

[@snehasish7]

Thanks for the video and the code.

Hi, thank you for your great efforts., can we use this VUMAT subroutine to define Kevlar-29/Epoxy without any changes in the VUMAT itself?

[@younesirvani4611]

Hi, Thanks for your helpful tutorial, can you explain why do we need to define eigen value and eigen vector in this subroutine?

[@alirezabayat6074]

سلام ... خیلی خوب بود آقا پیام ... ممنون ... فقط ممکنه بفرمایید روی آباکوس 2021 هم اجرا میشه یا نه؟

[@mohammedjamsheed5624]

Hi, thanks for this video. if you upload the video explaining how to write VUMAT code then it will be very helpful for me.

[@prateekm2222]

Good work

[@engineeringsimulation7364]

Thank you ♥

[@yyunchang]

Sir, where did you get the properties of the composite?? I want to use another composite material..!

[@engineeringsimulation7364]

carbon fiber/epoxy material properties is used for this example. you can search for your specific composite material properties in the related articles.

[@yyunchang]

@@engineeringsimulation7364 Thank you~~ I’ll search them

[@yyunchang]

@@engineeringsimulation7364 Can you share the source of the material property table on your video?

I watched your video and followed it well. Based on your video, I applied the conditions that I wanted to simulate. Consequently, the elements of plates and the elements of bullets overlapped, which is situation that cannot happen in reality. I applied the physical properties of Aramid through googling, and the speed was 200m/s. I want to know how I can solve this situation. If I can get your mail ID, I would like to send you a picture of simulation. Thank you!

Hi, Bro if you can upload the video explaining how to write VUMAT code then it will be very helpful and you will get really very large number of likes, share,s and subscriptions

[@vijayathithan]

Sir can you please share your mail id.. i have doubts on CFRP machining, ? can you please help me.?

[@alirezabayat6074]

Hello vijay, Could you please send me your E-Mail address?

[@MuhammadSalman-no7hb]

I am doing a project and need your help. Please provide your email or any other contact details. It will be so kind of you.
