A good Design is not complete unless it meets desired performance and qualifies for efficient manufacturing. Design of sheet-metal components demand the following, From a Design perspective - if sheet-metal can be used for intended design, their sizing & shape, choice of material, weight and cost.
From Manufacturability perspective - manufacturing feasibility of the designed shape, allowable thinning and wrinkling limits, addressing process constrains and importantly forming feasibility.
Leveraging Simulation to drive the design as it unfolds at the concept generation stage, helps design engineers to accrue downstream benefits upfront.
