Deformations of lipide membranes under the effect of ultrasound and local criterion of their disintegration

PossiЫe mechanisms of acoustic effect on cells are classified. The solution of а model problem on the effect of а plane ultrasonic wave on а spherical biomembrane and analysis of the resultant deformation substantiate the local significance of the criterion of damage the membrane suffers when its area is increased in excess of the permissible value.
