hello sir, I have 2 doubts not exactly doubts but need a direction and help can we add cohesive elements in this for delamination, matrix and fibre crack analysis? and how can we model curved composite laminate shell geometry design in abaqus?
Hello, yes, I believe you can use cohesive zone element to modelling the interphase effect. I believe you can, just try it out. On the second question of curved composite laminate shell geometry design, I do not have much to say. It is a thing of you trying it out and see what happens.
@MichaelOkereke Hello Sir, I have developed and analyzed lumber model in Ansys Workbench. Now I want to know how we can do bone remodeling in Ansys Workbench. Will you please help me? Thanks in advance.
Thank you so much for the video, it is very informative. However I have few questions to as: how to change the angle to 45 degrees. Can you please post the video of +- 45 same like you did for 0 and 90
This is okay... and similar approach as I did here. I will suggest you just input 45 degrees when you do the rotation instead of 90 degrees. Alternatively, look at this video and it will help you: ruclips.net/video/w9htHtQtzS8/видео.htmlsi=PJNMh-8_FOKMQ9x-
Very nice explanation sir. Please tell what is the general criteria here to set the size of an RVE. Earlier we know that how much volume fraction we have to kept and fibre diameter , but how to select the size of rve? Can you please elaborate this?
Hello @AnuragGupta-op7uz, thanks for this query. You are right in asserting that volume fraction and fibre diameter are model parameters that are independent of a chosen boundary condition. What we can change is certainly the size of the RVE. I have dealt with this question for a UD composite in this video: ruclips.net/video/2NFZ69zdSMM/видео.html I have also published an article about this here: doi.org/10.1016/j.commatsci.2012.12.036 in which I showed that for a UD composite, a good RVE size should be about a fibre size of six times the fibre diameter. This is about 90-micrometre for a 15-micrometre fibre diameter. I think this can be extrapolated to work for a BD composite considering that the building block of a BD composite - at the lowest level - is a lamina made up of fibres distributed within a matrix medium. However, it will be worthwhile to assess this fact numerically and determine whether that RVE size of six times the fibre diameter applies for a BD composite. It can be a little study that one can investigate too. I hope this explanation makes sense.
@@MichaelOkereke thankyou so much sir for this nice and detailed explanation. I will definitely see the video and the paper that you have shared with me. Thanks once again.
Thank you, Doc. Please, is it reasonable to perform a compression simulation of a UD RVE ?
Absolutely, it is certainly reasonable.

Hello @NiteshKumar, thanks for the comment. I am not able to provide the support you need here ... sorry! Good luck with the study.
Please teach modeling of thermoelectric materials.
Good suggestion!
