Abstract: It is very difficult to model an applicable microstructure for the open cell foams. Using the Python scripting language and the commercial code ABAQUS, the structures for regular Kelvin cell, regular Kelvin open cell foams and random Kelvin open cell foams were designed and modeled automatically. The methodology for modeling, the design and implement for the key algorithms in the process of modeling were presented. For the open cell Aluminum foam, the regular Kelvin cell open cell model and the random Kelvin cell open cell foams model were developed, respectively, and the mechanical responses of them under quasi-static compressive load were numerically investigated and compared.
