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

no promises but will try as writing UMAt is quite a bit of time investment.

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

I’m f you could send me details then I can see what I can do.

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?

it is explicit or implicit analysis? for explicit you may try mass scaling while keeping any eye on total energy and kinetic energy, as later shouldn't be significant. For standard analysis try stabilisation, and also contact controls and stabilisation options.

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.

Its not clear to me how they have normalised, as normalising means with some specific quantity. I can better comment after looking at the paper you have mentioned. Thanks
