Inflation and instabilities of a spherical magnetoelastic balloon Open
This study explores the instabilities during the axisymmetric inflation of an initially spherical magnetoelastic balloon, modeled as a magnetizable Ogden material, under combined internal pressure and a non-uniform magnetic field generated…

Hidden Dynamics of a Self-excited SD Oscillator Open
The present study explores the nonlinear dynamics of a self-excited smooth and discontinuous (SD) oscillator with geometric nonlinearity at the switching surface. Using a novel framework called hidden dynamics, introduced by Jeffrey, the r…

Nonspherical oscillations of an encapsulated microbubble with interface energy under the acoustic field Open
The practical applications of gas-filled encapsulated microbubbles involve inherent nonspherical oscillations under acoustic fields. The gas-encapsulation and encapsulation-liquid interfaces significantly affect the mechanics of the bubble…

Radial dynamics of an encapsulated microbubble with interface energy Open
In this work a mathematical model based on interface energy is proposed within the framework of surface continuum mechanics to study the dynamics of encapsulated bubbles. The interface model naturally induces a residual stress field into t…

Resonances of a submerged fluid-filled spherically isotropic microsphere with partial-slip interface condition Open
Motivated by the numerous applications of spherical shell models in micro and nano scales (such as microbubbles, bacterial cells, and viral capsids), we have considered the axisymmetric free vibrations of a spherically isotropic fluid-fill…
