Fìz.-mat. model. ìnf. tehnol. 2017, 25:151-156

Abstract

This paper is dedicated to the failure prediction for nanocomposite structural elements due to thermal instability under cyclic loading. It is based on the model of monoharmonic approximation and concept of complex moduli. The temperature and amplitude dependent complex moduli is used for the investigation of the dissipative heating influence on mechanical stability of polymeric nanocomposite rod subjected to both static and monoharmonic loading. Also, the influence of amplitude of the excitation loading and the volume fraction of nanofibers on thermal stability of the polymeric nanocomposite rod is studied.
