Abstract

Ecoflex silicone rubbers, served as the polymeric components of flexible electronic devices, actuators, energy converters, etc., are subjected to repetitive loadings during their service lives. The resulting stress softening and stress recovery phenomena can impose complicated impacts on their actua...
