Structured sheet metals are utilized for their high bending stiffness as semi-finished products in lightweight component manufacturing, particularly in the automotive sector. However, their widespread use is hindered by insufficient understanding of process parameters and design for further processing. The manufacturing process alters the formability of the initial sheet, subsequently changing the process limits for later forming operations. This work aims to identify the process parameters and limits for deep drawing, bending, and flat hemming of structured sheet metals produced via high-pressure forming. It delves into the material behavior of these structured sheets during forming, examining key influencing factors in detail. The impact of the structure on process limits is determined through experimental methods. Additionally, a finite element (FE) simulation method is developed for the process chain involved in producing components from structured sheet metals and is validated through experimental studies. The structured sheet metals are modeled using numerical forming simulations, which analyze their material behavior during the forming process. The application of research findings to complex components is illustrated with examples of sample components, such as the "base plate" for deep drawing and the "cap profile" for bending.
