A Study on the Sheet Metal Forming Process to Design Parameter of Inner Structured

Sandwich structures, which are composed of a thick core between two thin faces, are commonly used in many engineering applications because they combine high stiffness and strength with low weight. In this paper, through the FLD analysis according to the pattern changes, we have confirmed the deformed shape and formability distribution. Also, we have fabricated the dimple press mold according to the pattern changes, and obtained the dimple inner structure the forming experiments.
