A significant acceleration of degradation process is observed during occurrence of the self-heating effect, which has a character of mechanical energy dissipation and causes heating-up of structures. Following this, it is essential to evaluate a critical value of self-heating temperature at which a thermal domination of fatigue processes occurs. With a progress of degradation irreversible structural changes occur. In this study, an experimental evaluation of the degradation process was performed based on analysis of apparent thermal diffusivity of a composite structure at various selfheating temperature values. The obtained results show that the estimated apparent thermal diffusivity is a sensitive measure which allows for effective evaluation of structural changes caused by fatigue processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
