Hello mam, Your video is very useful and your teaching method also good, Mam can you make a video on visco-elastic material in writing code in UMAT relating to temperature parameters involved in it. Thank you

Pretty amazing tips 👌

Glad you like them!

Can you please explain me. How to write a umat subroutine for 1d beam element for plasticity.

hi, can I ask, how do you start writing the UMAT unit code? did you import that from edit keywords on model selection?

Dear Chathurika Thanks for useful video, please tell me how to add a new concrete material definition in abaqus; ? thanks

Hi Amr! I will be expanding the same code for soils soon. You will be able to repear the same for your concrete materail. More details: abaqus-docs.mit.edu/2017/English/SIMACAESUBRefMap/simasub-c-umat.htm Thank you.

Hi Chathurika...The video is nice.... i have written a UMAT based on a FRP composite. But the abaqus software is returning output as problem in compilation. Can you pls help me in this regard?.... 2) Before writing the UMAT should we load the ABA_PARAM.INC file?.....so as to not face compilation errors...if yes how can we resolve it?... I have been spending hours on this, but iam not getting result except frustration...Kindly guide me through this please...

Hi Mam, Your video is very useful. The mesh element size of your model is increasing towards right. Is there any specific reason for that? Can you upload a video on progressive damage in composite laminate if you are familiar with it?

Hi Ravindra! By changing the mesh size of the rigid body, the geometry of your object changes. So, it is expected to affects the results. You should decrease your mesh size (especially in the sharp parts and critical loading regions) to achieve a more accurate results. Generally, in finite element modelling the meshing size increases when it aparts from the loading point. www.comsol.com/multiphysics/mesh-refinement#:~:text=As%20these%20elements%20are%20made,the%20model%2C%20and%20the%20results. This link provides more details on meshing. Sorry, I'm not femiliar with progressive damage in composite laminate. Thank you.

Mam, I am doing simulations concerning cables. Abacus only showing up to elasticity. But I want it for elasticity. Can you please provide any reference for that. I want to capture after elasticity points with the help of subroutine with 1d elements ( strain hardening, necking, and rupture).

Hi, i would like to ask you some questions if you dont mi nd i will be grateful if you give me your email or anything i can contact you with thank you
