摘要：
The electromechanical coupling coefficient (EMCC) for the vibrations of inelastic piezoelectric bodies is defined. The effect of energy dissipation is taken into account by introducing integral loss characteristic. The definition of EMCC corresponds to Ulitko's energetic EMCC, which is interpreted as the limiting case when losses are neglected.
