Thermomechanical Stability and Thermal Fatigue Failure

This book is devoted to investigation of thermomechanical behavior and thermal fatigue failure of structural elements made from polymer¿based nanocomposite reinforced by nanofibers under combined monotonic and harmonic loading. To predict the time dependent and inelastic response of polymer matrix, a semiempirical phenomenological model is proposed. The effect of nanofibers on the overall effective inelastic response of polymer¿based nanocomposite material is carried out by using appropriate homogenization approach. The effect of interface between polymer matrix and nanofiber are modeled by the practical model as imperfect bonded.These results can be applied in prediction of the cyclic fatigue failure of polymer¿based nanocomposite structural elements due to thermal instability. In this book, frequency, temperature and amplitude dependent complex moduli will be used for investigating the influence of dissipative heating on the mechanical and thermal stability of structural elements made from polymer¿based nanocomposite materials.
