Efficient finite element modeling of acoustic radiation forces on inhomogeneous elastic particles.

An efficient and flexible numerical model is developed to investigate acoustic radiation forces on a particle of arbitrary size, shape, elasticity, composition and material characteristics. The model compares well with analytical solutions and has suggested useful results on shape dependency, and the effects of shear waves in ultrasonic particle manipulation. We present initial results for the forces on inhomogeneous particles using the example of a cell with a nucleus inside. [ABSTRACT FROM AUTHOR]
