文摘

The proposed solid model can better simulate the local stiffness of ligaments, compared to beam models in the literature. This model possesses the intrinsic scale effect due to random cell distribution in open cell foams. Structures formed by thousands of cells present a global constrain effect not addressable to a single cell characterization.
