Projections of Limiting States for Load-Bearing Structures of Reflectors Made of Polymer Composites.

This paper deals with limiting states typical for reflector antennas for terrestrial satellite communication systems. Reflectors made of polymer composites are studied. These limiting states are projected by results of the numerical analysis of the stress and strain states. The analysis is executed for reflectors under conditions of static and dynamic loading. It takes into account both overshoot of the state variables of allowed level and the processes of longterm structural material degradation. [ABSTRACT FROM AUTHOR]
