The temperature dependences of elasticity and shear moduli for TsTBS-3 and TsTSNV-1 piezoceramics were obtained by the resonance method for flexural and torsional vibrations of a specimen fixed on a single-sided support. The dependences were interpreted and their empirical polynomial relationships were derived. A region of constant elasticity and shear moduli was found for TsTSNV-1 piezoceramics in the temperature range of 330-360 K. The electrode-coated layer on the piezoelectric element was found to affect the elasticity moduli of TsTBS-3 and TsTSNV-1. The data obtained may be useful for the development of vibrational and piezoelectric transducers.
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.
