Theoretical analysis of ultrasonic wave absorption and elastic moduli for TeO2-V2O5-Sm2O3 glass system is presented. A correlation between low temperature ultrasonic relaxation parameters and other physical (elastic) properties for this glass system was achieved according to a model presented by Bridge and Patel. Correlation coefficients greater than 96% were obtained indicating that correlations between ultrasonic attenuation and activation energy at low temperatures and the bulk modulus of this glass system at room - temperature (through the two crucial structural parameters, number of anions and anion-cation force) exist.
