샌드위치판재의 U-bending 공정에서 굽힘하중식의 검증Verification of load equations for sandwich plates during U-bending

To verify the load equations, the load-stroke curves of the load equation that were analytically derived for sandwich plates were compared with those of the simulations in the case of the total thickness of 3 mm, the thickness of the face sheets of 0.5 mm, a gap between attachment points of 1.5 mm, and a thickness of the core element of 0.8 mm. The results of the comparisons showed that the overall analytic loads enable the prediction of the numerical loads irrespective of the change of the clearance, the radius of the die, and the radius ratio.
