Abstract: The equivalent elasticity modulus, equivalent yield strain and equivalent plate stress of V-type folded core could be got using surrogate models. Based on the surrogate model, a homogenized equivalent model of V-type folded core under static/quasi-static compression was set up. The calculation results show that the mechanical properties of the original structure are simulated well by the homogenized equivalent model, and the computing cost is greatly reduced. The equivalent model in this paper provides an efficient way to calculate or optimize the property of folded core applied in structures, especially in anti-crash and energy absorbing structures.
