Can any one help me in the modelling of composite material damage, using damage mechanics techniques?

what is the simplest definition of ion exchange capacity

What this unit identifies for the ion exchange capacity ca. 0.92 meq. g-1. I am a newcomer in the membrane area. I just started. I highly appreciate your help

Can we classify HV and LV lines based on line length?

I have dataset which shows the length of power lines. I need to classify the lines based on the line length. Is there a rule to classify the High voltage (HV) and low voltage (LV) lines based on...

Hi Elsisi,

I hope this will help you a lot, you can find some other tutorial on google as well.

Thank you Riaz, It is really a helpful data, this that I began with. I am working with Ansys, I am forced to write user material subroutine (usermat) based on numerical models. I need some samples or a code based on damage mechanics or any can help me in ding that.

Hi Alaaeldin

Maybe this paper can be of interest to you. It is about a mesoscale damage mechanics approach that has been implemented in Abaqus. At least, that will provide you some basic equations about about to model mesoscale damage associated with transverse cracking, fiber/matrix debonding and so on..Please contact me if any question.

Good luck

Thank you very much.
