When a composite material is subjected to a time varying strain field, energy is dissipated because of the thermoelastic effect (elastothermodynamic damping or ETD). Evaluation of ETD in particle-reinforced MMCs has been reported in literature. These works follow a quasi-static approach. In the present work, a full dynamic solution for the energy dissipation is obtained, using the entropic approach. It is observed that the specific damping capacity predicted by the dynamic solution deviates from the quasi-static solution at high normalized frequencies, for low inclusion radius and low volume fraction.

Innovative companies generally establish linkages with other actors and access external knowledge in order to benefit from the dynamic effects of interactive processes. Using data from 198 furniture and software firms in Indonesia, this study shows that the quality of interaction (i.e. multiplexity) as indicated by the depth of knowledge absorbed from various external parties and intensity of interaction (i.e., tie intensity) are better predictors of product innovation than the diversity of interaction.
