With the development of various multi-composite materials, there are several methods to study the mechanical properties of materials with complex microstructures. As a typical multi-composite material, foam concrete’s mechanical properties and research methods are also widely concerned. To predict the mechanical properties of foam concrete more quickly, we use Python software to realize the random generation of foam pores to establish a random three-dimensional geometric model of foam for many foam concrete materials. Based on the random foam three-dimensional geometric model, the equivalent parameters of foam concrete are calculated by the method of calculating the equivalent parameters of materials in mesomechanics. The relationship of equivalent material parameters between porosity and foam pore diameter is sought. Finally, the tensile calculation of a foam concrete cube with a cohesive unit is carried out to study its stress-strain distribution and the initiation and development of cracks.
