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).

Abstract: A combination comprising a bed of a particulate copper-containing catalyst and, a guard bed of a particulate composition containing a) lead and/or at least one lead compound that reacts with hydrogen chloride and b) a support therefor. The lead compound is preferably lead nitrate. The combination is of particular utility for the low temperature shift reaction wherein carbon monoxide is reacted with steam to produce hydrogen and carbon dioxide.
