Hi,
I am doing a simulation of a ball striking a plate that has a lattice structure within it. (See Plate.jpeg) The results are shown in (Result.jpg) I Then took a unit cell and brought it into ANSYS material designer to obtain the effective properties. These will give me the young's modulus (E1, E2, E3), shear modulus (G12, G13, G23) and 3 poison's ratio. However, when I used these effective properties, my simulation result for the homogenized structure is vastly different. (see homogenize_result.Jpg) Is this because homogenization only gives the effective elastic properties and not the plastic properties? *I used the same plastic properties for the homogenized simulation as I did for the actual lattice impact simulation. Thanks in advance! Last edited by Jwes; February 9, 2020 at 21:58. |
