Random Foam Meso-Model and Mechanical Properties of Foam Concrete
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.
期刊介绍:
Strength of Materials focuses on the strength of materials and structural components subjected to different types of force and thermal loadings, the limiting strength criteria of structures, and the theory of strength of structures. Consideration is given to actual operating conditions, problems of crack resistance and theories of failure, the theory of oscillations of real mechanical systems, and calculations of the stress-strain state of structural components.
