What is it about?
Hysteretic heating effect in polyamide 66/hectorite nanocomposite has been investigated under bending strain control mode using a custom-built bending fatigue test setup in laboratory environment. Fatigue behavior predicted from dynamic mechanical analysis results using coupled structural/thermal finite element analysis is fairly in agreement with the experimental one. Fractography studies were used to corroborate experimental results.

Why is it important?
An increased use of thermoplastics in components and structures that are subjected to cyclic loads necessitates a specific attention to variables that affect the hysteretic heating.
Perspectives
This is a good piece of work on fatigue behavior of polymer nanocompsoites with experimental, numerical and fractogaphy studies.
