Sheet Metal Forming in OpenForm

OpenForm is a solver-independent graphical user interface (GUI) designed to aid the generation of input decks for numerical forming simulations as well as to evaluate the numerical results in an intuitive and simple fashion.

Based on an internal standardized metalanguage, the so-called "OpenForm Process Language" OFPL, the mechanical process to be simulated is described consistently regardless of the required solver-specific numerical parameters. Thus, the forming process described in OpenForm can be used simultaneously with different solvers.

The structure of the forming process is captured hierarchically using graphical templates and then translated and exported in the corresponding solver nomenclature using internal converters of OpenForm. The basic components of these process templates are formed by "items", which are in turn assembled in process "steps" to ultimately become "operations". For LS-DYNA, there already exist many such templates in OpenForm to deal with cold and hot forming of traditional form blanks as well as tailor rolled (TRB), welded (TWB) or sandwich blanks.
