Abstract: Methods and systems for analyzing stamped parts having a final shape for a vehicle are provided. A method includes receiving data for the stamped part; producing a computer simulation based on the data; determining a wrinkling index (WI) for the stamped part in response to the processor producing the computer simulation; determining whether an element under analysis is located at a trimmed edge of the stamped part; when the element under analysis is located at a trimmed edge of the stamped part, determining a stretching index (SI) for a trimmed edge portion, or when the element under analysis is not located at a trimmed edge of the stamped part, determining a SI for a plane stress portion in response to the processor producing the computer simulation; comparing the SI to a SI threshold and/or comparing the SI to the WI; and generating, using the processor, a uniform failure index (UFI).
