| Abstract: | The electric conduc tivity and piezoresistivity of ortho tropic materials are studied based on the electrostatic theory and the clas sical lamination theory .The correlat ion between the piezoresistivity coe fficient and piezoreconductivity coe fficient in the Cauchy strain is deriv ed. Finally, a lamination theory of pi ezoresistance in composite laminate under in plane stresses state is put forword. |
