Numerical model of shear module of alginate micro-beads under ultrasonic thermal effect / 军事医学

ABSTRACT

Objective To establish a numerical model of the shear module of alginate beads stimulated by ultrasonic sound.Methods The compression ratio and force of alginate beads were recorded with the compression test .The shear module of beads was measured with a Hertz model .When to alginate beads were stimulated ultrasonically for different durations , the ultrasonic stimulation power , ultrasonic pulse ratio , and changes in the shear module and solution temperature were measured.Results Temperatures in the solution and shear module of alginate beads increased under different ultrasonic stimulation conditions .Modeling analysis revealed the relationship between the shear module of alginate beads and the corresponding temperature .The shear module of beads was in a quadratic equation with temperature (20℃analysis showed that the function had a good predictive and descriptive effect .Conculsion This function can be used as a good predictive model of the shear module of alginate beads at different temperatures .The results can facilitate the application of alginate beads to medical and biological research .
