摘要：

Gallium-based liquid metal-elastomer composites have attracted more and more attentions owing to their combination of high flexibility, electrical conductivity, and excellent bio-compatibility. Computational micromechanics analysis will be conducted on their mechanical response, and the impacts of surface tension and Ga2O3 shell are considered in detail. Based on a double-inclusion configuration, a three-level Mori-Tanaka mean field model is developed to predict the overall modulus and then an incremental homogenization formula is established for the predication of non-linear stress-strain relations. The experimental results and unit cell-based FEM modeling are also employed for verifying the analytical model.
