The boundary-element method (BEM) is used to simulate the bubble growth, contraction and collapse near the deformable sphere. The finite element method (FEM) is used to calculate the sphere response to the fluid pressure induced by the bubble oscillating. The interaction of the oscillating bubble and the deformable sphere is simulated via the coupled BEM-FEM. A good agreement between the numerical simulations and experimental observations is achieved. Parametric studies are further carried out for the oscillating bubble near the deformable sphere with different material properties. The results show the influences of the sphere stiffness, the bubble-sphere size ratio, and the relative distance of the bubble and the sphere, on the bubble collapse and the sphere deformation. From the results obtained, some insights to the problem of an oscillating bubble near a deformable sphere are deduced. 000014528 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000014528 653__ $$a 000014528 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000014528 720__ $$aGong, Shi, Wei 000014528 8560_ $$ffischerc@itam.cas.cz 000014528 8564_ $$s165294$$uhttps://invenio.itam.cas.cz/record/14528/files/TS.FM06-1.06.pdf$$yOriginal version of the author's contribution as presented on CD, page 784, code TS.FM06-1.06 . 000014528 962__ $$r13812 000014528 980__ $$aPAPER
