change in resistance of CFRP with impact load acting on it

Please login with a confirmed email address before reporting spam

Dear All,

I am working on a project, where i intend to calculate the change in resistance of the CFRP cylindrical specimen when subjected to the impact load along longitudinally. i chose to use piezo resistive physics.
Here are few concerns of mine.
1. In material library when i choose carbon fibre, It asks me elasticity matrix.
2. If i wish to use the separate physics like AC/Dc > electric current and solid mechanics, how can i couple the two physics , where i want change in resistance due to impact load.

If any other suitable physics available, please suggest me.

Thank you all in advance

Regards
Sudarshan
