Development of a new method for producing plane expanded metal by laser cutting and forming of metal plates under uniaxial tension

摘要

The on-going trend to lightweight construction leads to a special focus on plane lattice structures as an alternative for solid metal plates. They demonstrate similar mechanical properties while taking up only a fraction of the normal material input and are thus economically favourable. Additionally, they fulfil functional and design aspects and therefore are used by several industries like the automobile. Nevertheless, the two most common types of lattice structures - perforated metal plates and expended metal plates - are either waste intensive or uneven and hence require additional rolling of the metal plate.
