...Tom Zhang; Y. Lawrence Yao Metal foam is an excellent lightweight material with promising industrial applications. Laser forming has been studied and shown to be a viable non-contact method to shape metal foam panels into desired geometry without fracturing the foam’s cellular structure. However...

...Tom Zhang; Yubin Liu; Nathan Ashmore; Wayne Li; Y. Lawrence Yao Metal foam is light in weight and exhibits an excellent impact-absorbing capability. Laser forming has emerged as a promising process in shaping metal foam plates into desired geometry. While the feasibility and shaping mechanism has...

... analyzed. This study was focused on laser forming of metal foam sandwich panels into non-Euclidean (3D) geometries. It was investigated whether the bending mechanisms and process parameters identified for 2D laser forming translate to 3D deformation. Additionally, the impact of the laser scan length...

... the road toward a more economical implementation of sandwich panels, by showing that the material can be successfully bent up to large angles using laser forming. The study also developed a fundamental understanding of the underlying bending mechanisms and established accurate numerical models...

...L. Casamichele; F. Quadrini; V. Tagliaferri The present work is an experimental investigation on the laser forming process of aluminum alloy and stainless-steel thin sheets. A high-power diode laser (HPDL) with a nonsymmetric spot configuration was employed at medium and low scanning rates...

...Peng Cheng; Yajun Fan; Jie Zhang; Y. Lawrence Yao; David P. Mika; Wenwu Zhang; Michael Graham; Jud Marte; Marshall Jones Laser forming (LF) is a non-traditional forming process that does not require hard tooling or external forces and, hence, may dramatically increase process flexibility and reduce...

...Peng Cheng; Yajun Fan; Jie Zhang; Y. Lawrence Yao; David P. Mika; Wenwu Zhang; Michael Graham; Jud Marte; Marshall Jones High-intensity laser beams can be used to heat and bend metal plates, but the mechanisms of the laser forming (LF) process are not well understood or precisely controllable...
