Dear Professor Ahmed Ebid. Thank you for your question. However,I am not expert in Experimental Engineering. I am rather expert in Computational Engineering. So, I recommend you the Group of Experimental Engineering of Concrete Structures of our Department: Professors George Manos,Yannis Tegos, Makis Stylianidis, Christos Ignatakis, Alex Tsonos and particularly the young Professor MsThermou ,who has coworked with Professor Amr El Nashai. I hope that you can find them in Research Gate. Sincerely yours Panagis G.Papadopoulos.
