The effect of waviness of a helical inhomogeneity on its stiffness- and conductivity contribution tensors

The paper provides computational results for the stiffness- and conductivity contribution tensors of a helical carbon inhomogeneity embedded in an epoxy matrix. We analyze the effect of waviness of the fiber in a broad range of its variation. It is shown, in particular, that dependence of the components N-1111 and N-2222 of the stiffness contribution tensor on the waviness parameter is almost the same as the one for the components k(11) and K-22 of the conductivity contribution tensor, respectively, implying certain cross-property connection. In contrast, the waviness-dependence of the components N-1122 and N-1212 is entirely different and is non-monotonic. (C) 2017 Elsevier Ltd. All rights reserved.
