Bubble dynamics and cavitation damage to curved elastic boundaries

Abstract Prediction of cavitation damage to the solid boundary is crucial in application ultrasound. The goal this study investigate potential for a bubble cause mechanical effects on curved elastic and contribute understanding mechanisms bubble-structure interaction. Effects surface curvature are studied using finite volume method. In oscillatory migration bubbles bottom boundary, there several shape modes at same time. wall stress/deformation produced by impinging jets increases with parameter α. dynamic behaviors deformation have no significant effect as Young’s modulus equals or exceeds 60 MPa. Boundary generated tensile compressive stresses during collapse may be basic mechanism erosion. Due lack visual observation research acoustic effect, key ultrasonic missing. Therefore, importance dynamics paper self-evident
