Predicting thermal and mechanical performance of stochastic and architected foams

• Properties of metal foams are sensitive to not only porosity but also topology. Thermal conductivities commercial stochastic almost isotropic. Architected have 103% higher thermal conductivity than foams. stiffer and absorb 265% more energy This study conducted pore-scale simulations estimate the stagnant mechanical performance architected The 5-, 10-, 20- 40-ppi aluminum were estimated be 6.74, 6.49, 5.97, 7.16 W/m/K, respectively. depended mainly on was a strong function pore size. models simulated Al foam along three orthogonal directions 7.16, 7.92, 7.56 respectively, indicating isotropic nature. Compared with foams, triply periodic minimal surface showed conductivity, 488% stiffness, absorption capability. findings reported here provide fundamental understanding interplay between architecture open new avenue create multifunctional
