Numerical and Experimental Study of Quasi-Static Loading of Aluminum Closed-Cell Foams Using Weaire–Phelan and Kelvin Tessellations

Study of porous materials, in particular closed-cell foams, has always attracted researchers’ interest due to the advantages these materials offer applications where low weight, buoyancy, insulation, or energy absorption is importance. In this study, quasi-static compressive experimental tests are conducted for low-, medium-, and high-density aluminum foams their mechanical properties obtained. addition, two types lattice structures based on regular repeating unit cells (Kelvin Weaire–Phelan) modelled suitability predicting behavior configuration evaluated compared. Due irregular structure cast it computationally very expensive reproduce numerical models with similar structural topology. Using tessellation method can be a step forward investigating various parameters affecting foams. The results indicated that as compared Kelvin models, Weaire–Phelan better mimic deformation manufactured specimens. On contrary, obtained from general closer results. study also showed foam density increases, densification strain decreases, while all other (elastic modulus, yield stress, plateau capacity) increase.
