Abstract The representative volume element (RVE) model of epoxy resin composites with random distribution of hollow glass microspheres was established. The cohesive element is used to model the behavior of interfaces in composites. The influence of the relative wall thickness and vo-lume fraction of the hollow glass microsphere on the stress-strain curves and yield strength of composites were studied by numerical simulation. The discrepancy of stress distribution in composite materials was analyzed when the relative wall thickness of glass microspheres was different. The effect of interface strength on the yield strength and stress distribution of composite foams was also investigated. The study shows that the numerical simulation results considering the interface are in good agreement with the experimental data in the relevant literature. The relative wall thickness of glass microspheres has a critical value about 0.06. When the relative wall thickness is less than the critical value, the yield strength values of composites decrease with the increase of microspheres content. On the contrary, it increases. The stress distribution in composites varies greatly with the relative wall thickness of microspheres. Interface plays an important role in the strength and stress distribution of composites. The yield strength of composites is linearly correlated with the content of weak interface. Weak interface makes the stress distribution of matrix around microspheres change greatly.
