Thermal and mechanical stabilities of Core-shell microparticles containing a liquid core

Thorough understanding of the behaviour core–shell microparticles with a liquid core is essential for determining their performance in applications under different operation conditions. This paper reports particles thermal and mechanical loads. First, we formulated an analytical model heating process microparticle core. Next, utilised axisymmetric elastic spherical shell upon compression to describe deformation microparticle. Finally, conducted experiments validate these models. Both models agree well experimental data. The maximum temperature can withstand depends on liquid, geometry, material shell. critical force before rupture Poisson’s ratio thickness relative outer radius. increase increasing thickness.
