摘要： Sheet metal is provided as a template to create a finished product. After various metal transformation techniques are performed on the sheet metal, the sheet metal may be converted to the finished product. The sheet metal manipulation may encompass different techniques, such as thinning, bending, cutting, and the like. The manipulated sheet metal may be sourced for various products, such as a body of a vehicle. The aspects disclosed herein combine various tests employed to detect the integrity of the sheet metal transformation into a singular output.

摘要： A method of manufacturing a structural component having tailored material properties by applying an IR-absorbent coating to a substrate formed of a ferrous-based, aluminum-based, magnesium-based, or fiber reinforced composite material is provided. The coating is preferably formed of iron oxide (Fe3O4) decorated multiwall carbon nanotubes. Alternatively, the coating is wax-based or polymer-based and includes TriSilanollsooctylt POSS and additives. Different coating compositions may be applied to different zones of the substrate so that the emissivity coefficient varies along the substrate. The coated substrate is heated and formed between a pair of dies to achieve a complex shape or features. The IR-absorbent coating increases the infrared absorption rate during the heating step, which improves formability of the substrate. The iron oxide (Fe3O4) decorated multiwall carbon nanotubes can also be applied to an engine component to increase the thermal efficiency of the engine by reducing friction and enabling the use of light weight materials.

摘要： A method and system for detecting edge cracks of an element of a sheet metal product is provided. The method includes calculating a first stress associated with a forming process employing a first die; calculating a second stress associated with a finishing process employing a second die; combining the first stress and the second stress to formulate a total stress; simulating the sheet metal product to produce a benchmark stress; and comparing the total stress and the benchmark stress to determine if the element predictively contains edge cracks.
