A method is provided for determining a pressure distribution of a molding tool device (1) for reshaping a sheet metal component (2). The pressure distribution represents a load on the sheet metal component (2) caused by reshaping in the molding tool device (1). The method includes introducing a piezoelectric material (3) into a raw material (12) of the sheet metal component (2) to form a composite sheet metal component (4) that provides an electrical voltage under mechanical loads. The method proceeds by arranging the composite sheet metal component (4) in the molding tool device (1) and reshaping the composite sheet metal component (4) with the molding tool device (1). The method then uses at least one sensor device (5) for detecting spatially resolved electric voltage signals that emanate from the composite sheet metal component (4) during the reshaping and determining the pressure distribution using the detected spatially resolved voltage signals.
