- Abstract
- When using a supporting laser patterning method, it is possible to adaptively tailor the strength variations and formability of a pre-fabricated single panel. This paper focuses on the effect of line and geometrical laser patterning on the strength enhancement and material behaviour of steel sheets. To validate the performance of the laser patterning specimens, a tensile test for evaluating the in-plane deformation behaviour and a 3-point bending test for out-of-plane have been conducted while maintaining the area fraction for the laser-treated area. Close-type laser patterns, e.g., 0 degrees, auxetic, and honeycomb, not only induce a substantial increase in strength but also enhance bending resistance without sacrificing the springback tendency of the initial sheet material.
