Abstract:

To promote the aluminum honeycomb cell scaling CAE model calibration efficiency, which is mainly affected by the difficulty of deformation mode recognition, the plastic strain contour plot vision based deformation mode criterion is proposed in this paper. The new method, along with the traditional stiffness criterion, is integrated into an automated script by python, which is applied in the ACMDB aluminum honeycomb cell scaling CAE model calibration process. The results show that the proposed deformation mode criterion is highly correlated with the aluminum honeycomb compression deformation mode, and the developed automated script can effectively reduce the dependence of the calibration process on engineers.
