Is there a software that can predict the reliability of a mechanical component, based on the type of loading and incorporating all the environmental effects like corrosion and hydrogen embrittlement etc.

Thank you! This is very helpful

thank ypu sir for sharing this helpful video, sir i have question about meshing in abaqus , can you help me pleases

Can you please make a video on doing Plane strain compression test using cpfem?

Sir, do you still reply to email? I'm facing some problems while using Abaqus. If you could help me then it would be good.

Thank you so much sir 🙏🙏

Thank you sir ❤❤

Good explanation Doc....❤

Hello, I have a quetion but its not related to this topic. Can the CPFEM subroutine be used without the iteration method?

Speaking of 3 minutes, if you want this channel to become more popular, you need to take 3 minutes to listen to your audio recording, and another 3 minutes to rerecord when the audio quality is this poor.

thank you sir for this helpful video,can you please share with me this file cao

Sir, please share the reaserch paper from which you selected data

Sir how to plot " pressure vs strain" curve?

Thanks for the tutorial Prof. However I have something confused me, as per DNVGL F110 it is mentioned that the global lateral buckling will be happened if the compressive initiation force already reached (prior to that it will be pre-buckle configuration.After the initiation compressive force has beeen reached there will be a sudden decrease in compressive force, which I understand will be the post buckle configuration. Not sure how to relate this with the modelling explained here or how to model this DNVGL criteria of buckling. Appreciate if I can have an enlightment.

Please can you make a video for the damage in FGM using UMAT?

Awesome, thank you so much for your efforts

Hello, i am a Masters student and i am also working during my internship on these kind of cubic geometries.. i am here still learning about the UMAT and Fortran stuff, i tried to copy the code from the video to execute it the same way as you did and alot of error message have just appeared.. and i think it is an issue of syntax.. Could you please send me the subroutine .for file that you used in this video to know and correct my mistakes ? If you also can send the pure elasticity UMAT, i would be very grateful !

Thanks !!!!!!!!!!

I am getting an error In Model: Model-1, Regions of the part "Part-1" have not been assigned a beam orientation. Use "Assign-->Beam Orientation" in the property module to assign a bean orientation. When I submit the Job

Thank you for making this video. I am facing problem in implementation, the subroutine has no issue during compilation. But the Abaqus abort with error "ErrElemZeroHourGlassStiffness". I am using the same model for UMAT as used for Abaqus default material by changing it to user material. Also, the strain crements are zero. Appriciate your assistance.

Why it is taking longer time for run ?????

sir i hope you are fine i am a student of mechanical engineering i have done few simulations during my studies but i face the problem during setting the step time. every time i randomly selected the step time for the simulation but i face the time increment error. sir can you please tell me how to exactly the set the step time to avoid this error

Hi, I am interested in the heating and cooling cycle to simulate shape recovery. May I know how I can achieve that?

*** Error:ABAQUS/Standard rank 0 failed to allocate memory *** ERROR CATEGORY: ASSEMBLY I am getting this error, what could be the reason? My time increments are very small 1e-5, and the odb file till now is taking 55gb disk space. could this error mean that I require to run this analysis on a machine with more physical memory?

Can you please make a video for the damage in FGM using UMAT?

Thank you very much. Your videos are always the best, and I can't wait for the next video.

can you explain, why you use 'Ductile Damage Model' and not 'Johnson-Cook damage model'???

Awesome, thank you very much for your efforts. Please can you make a video for damage in the FGM using UMAT

Can CPFEM be used with a surface-surface contact pair or should we use 3D contact? if yes what should be the appropriate timestep for it? A paper "Comparison of the implicit and explicit finite element methods using crystal plasticity" By Harewood states convergence is not achieved when using Contact Pairs with CPFEM model.

Wonderful tutorial sir ! Just out of curiosity , at last step what is the reason behind multiplying step increment time with 50 MPa and calling it as failure pressure.

Many thanks for uploading this video.

Thanks for your useful tutorials. I can't find any tutorial about UEPACTIVATIONVOL Abaqus subroutine anywhere, could you make a video about it?

Hi, in abaqus in CP the results like stress are displayed in the local coordinate system of each point. Do you know field lf stress in the gui are then in the global coordinate system

Why you did not use the composite lay up?

I think something might be missing in the tutorial sequence. I have tried to reproduce it in Abaqus 2020 and 2023 but there is always an error and the simulation does not even start. I have tried different solvers such as Riks, and Coupled temp-displacement (both in steady-state and transient). I have tried elements B31, B31H, PIPE31 and PIPE31H with no results at all.... What version are you using to run these simulations? I thik there might be a bug in these Abaqus versions...

My plasticity model works for time step 1*10^-6, when i run my nanoindentation simulation using that material, the computation time is insanely large (100+ days), what can I do to reduce it?

can the above analysis be done by ansys

Sir,In Abaqus, I'm performing an explicit coupled temperature-displacement analysis. In my analysis it requires normalizing of time. The author of the paper says "We normalized time along with the normalization of thermal conductivity with its reciprocal in order to bring down the computational cost of simulations. The obtained solution using normalized time was again converted back to normal time accordingly " . Sir, How can I return to regular time in Abaqus after normalizing? My thermal conductivity is 10 and my step time is 36000 seconds according to the paper. Does my analysis require me to inverse these values in order to normalize? Is this the correct way? Should I additionally normalize the time that I utilized as a tabular input time(0-36000 sec) for my boundary condition if I do this?. I would be very grateful if you just share your thought regarding my query.

Thank you professor! Your manual is very helpful. But I got a problem, when I simulated a similar task some elements with low temperature (around 3-10 Kelvins) occured during analysis. This problem aborted my analysis. What can cause this? Thank you

Bro warning, Displacement increment for contact is too big, how to slove

THANK YOU SIR FOR THIS VERY INTERESTING VIDEO, SIR I HAVE ONE QUESTION , i have modeld hollow sphere , then i' applied radial displcement at inner surface ,when i submit the job i get error , can help me please to solve this error , pleaes sir can you make make video for this problem

I found this video very useful. Thank you for uploading it. I have to simulate nanoindentation experiment, I am trying to match laod displacement curve of simulation and that of experiment, but in vain. How can I find tangent modulus and yield strength of my film? I have elastic modulus (160GPa) and hardness (7Gpa)? 16:08

You know what? I am a regular viewer of your RUclips Channel. I have seen all your videos and your content qualities are very good. I learned lots of things from you. Your channel has great quality contents but still it is not delivering its right audiences due to SEO problems. You should focus on your SEO so that You can get a big fanbase. Thanks.

Sir, can you please make a video how to model Multiwell horizontal HYDRAULIC fracturing using Abaqus XFEM
