This paper aims at characterizing the piezoresistance behavior in a carbon fiber reinforced plastics (CFRP) unidirectional laminate under mechanical loading. A two-dimensional model is proposed using a DC circuit equivalent to an electric resistance network in the laminate to predict the resistance...
